To prepare for a depression visit when low mood has lasted a long time, record the usual pattern, better stretches and recent changes on the same timeline. Give each better stretch a rough beginning and ending, describe what actually improved, and leave uncertain days unknown. Bring the notes you have; you do not need a diagnosis or two years of daily entries before asking for help.
Start with a useful history, not a self-test
This guide is for adults preparing for a primary-care or mental-health appointment, including people who recognise the terms persistent depressive disorder or dysthymia from a chart. The task is to explain a long history more clearly, not to decide whether that diagnosis applies. If a clinician has already supplied a diary, follow their instructions instead of creating another tracking task.
A long-standing low mood can feel so familiar that “I have always been like this” becomes the whole explanation. Add what that sentence means in daily life: getting through work but withdrawing afterwards, struggling to start tasks, or feeling persistently discouraged. Function matters even when you still attend work, and a familiar pattern deserves attention without being treated as a personality verdict.
Keep three time windows visible: the usual pattern over months or years, the better stretches within it, and what happened in the last two weeks. These windows can tell different parts of the same history. A recent improvement should be recorded honestly without erasing earlier difficulties, while a worse fortnight should not become your description of every previous year.
| Time window | What to write |
|---|---|
| Long-term pattern | Approximate onset, usual mood, everyday effects and how reliable the memory is. |
| Better stretches | Rough dates, what improved, what remained difficult, and whether the ending is known. |
| Last two weeks | Recent mood and function, changes from the baseline, and anything new or worsening. |
What a two-week form cannot show
The PHQ-9 research paper describes a questionnaire focused on the preceding two weeks. Answer a clinic form for the period it actually asks about, rather than blending years of memory into those responses. Bring the longer history alongside it so the clinician can interpret current symptoms in context.
For example, someone may describe fewer difficulties during a quieter fortnight while recalling a low baseline throughout several earlier years. Those accounts are not automatically contradictory, and the short form remains useful. A two-week questionnaire on its own cannot reconstruct the onset, interruptions or longer course; this log supplements the conversation rather than proving the form missed a diagnosis.
The four columns that keep better stretches visible
Use the same brief fields in a notebook, phone note or the record below: date or period, mood and function, improvement status, and whether the stretch is ongoing or has ended. Add a certainty note when the memory is rough. “Around the move” and “ending unknown” are more useful than exact dates invented to make the sheet look complete.
| Column | A useful entry |
|---|---|
| Date or period | “Around my job change in spring”; use a rough month or life event when an exact date is unavailable. |
| Mood and function | “Less discouraged; still avoiding friends”; separate feeling better from everything having cleared. |
| Better, unchanged or unclear | Choose a description of the observation, not a clinical remission label. |
| Stretch ending and certainty | “Still ongoing,” “low mood returned after the holiday,” or “end date unknown”; identify recalled details. |
A better day does not describe the whole month
A good afternoon, three easier days or a better week belongs in the timeline because it is part of your experience. Record what improved and what remained difficult instead of calling the whole month symptom-free. Do not decide that the long-standing difficulty has ended merely because a pleasant event was possible, and do not dismiss a genuine improvement either.
The fictional example below uses selected periods from a month, not a complete daily diary or a patient case. Three better days are surrounded by low mood, with one day that cannot be recalled. The unknown day stays unknown; it is neither added to the better stretch nor counted as a low day.
| Selected period | Observation | Stretch note |
|---|---|---|
| 1–10 June | Low and discouraged; chores took extra effort. | Recalled pattern; not every day individually recorded. |
| 11–13 June | Three easier days; enjoyed a walk, but sleep stayed difficult. | Improved compared with baseline; not recorded as fully symptom-free. |
| 14 June | Cannot remember. | Unknown; do not bridge the surrounding periods. |
| 15–30 June | Low mood returned; cancelled two social plans. | Approximate return date; no longer stretch established by this sample. |
If a stretch is still continuing, write “ongoing” and describe it as it is today. If low mood or the difficulties you were recording return, note the approximate return point. You do not need to wait for a particular number of weeks before opening or closing an observational entry.
Why the two-month wording is not a logging rule
Clinical duration criteria are context for the appointment, not instructions to wait before recording a change. The SAMHSA criteria summary includes a two-year adult duration and considers interruptions longer than two months within the relevant mood-and-symptom pattern. It also includes other requirements and exclusions, so counting time alone cannot establish persistent depressive disorder.
“Feeling better” does not necessarily mean the relevant symptoms were absent, and two calendar months should not be silently converted into a fixed number of days. Describe the improvement, its approximate duration and what you cannot remember. A clinician can ask about symptom-free intervals, other symptoms and alternative explanations; the record should not issue a threshold result.
Build the earlier years from anchors, not a perfect diary
Choose a few events you reliably remember: a move, a job change, a holiday or a period at college. Write the mood pattern around each anchor, then mark the time between them as uncertain if necessary. This reconstructs a usable history without pretending that a calendar, photo or employment date proves your mood on every day.
For a fictional year, a person might write “spring job change: low most weeks,” “summer holiday: easier for roughly a week, but still low energy,” and “winter: withdrawing after work again.” The job date is known, while the mood dates are recalled estimates. That distinction belongs on the sheet because remembered events can locate a period without establishing its exact boundaries.
- Use an event you actually remember rather than guessing a precise onset date.
- Separate notes made at the time from details reconstructed later.
- Keep uncertain intervals visible; missing notes do not show what happened.
- Choose a few representative periods instead of trying to recreate every day.
You can also write “before adulthood, exact age uncertain” if that is the honest starting point. Clinicians may ask about age at onset, but there is no need to force an early-or-late label into your own account. If you cannot name the beginning at all, describe the earliest period you can recall and how confident you are about it.
What to do with forgotten days
Use “unknown” when you cannot remember a day or interval, and avoid filling it from how you feel now. If a later message or diary entry helps, correct the note and say where that information came from. Someone else’s recollection can add context, with your agreement, but it should remain distinguishable from your own observation.
An uncertain day can interrupt confidence about the boundaries of a better stretch without proving that symptoms returned. Write “better on either side; middle day unknown” when that is all you know. Leaving a gap in the evidence is more useful than producing an apparently seamless timeline from guesses.
Show a worse month above the usual baseline
Keep a recent worsening separate from the long-term pattern so the clinician can see what changed. For instance, “usually discouraged after work for years” and “this month, stopped replying to friends and struggled to prepare meals” describe two layers. Neither sentence assigns a diagnosis, and a worsening problem deserves care without waiting to see whether it fits a label.
Add sleep, appetite, energy, concentration or self-talk when those changes help explain function, rather than completing a symptom checklist to qualify for PDD. If missed meals are part of the change, the skipped-meal appointment log can preserve what was eaten, skipped or unknown. If the concern is eating more on particular days, the separate overeating-day appointment record addresses that different observation.
When eating difficulty appears around anxious situations, the anxiety appetite-loss record offers fields for the situation, body sensation and later hunger. Use a supporting record only when it helps explain your own concern; there is no need to run several diaries at once. Bring the patterns together without deciding that anxiety or depression caused the change.
Create a short visit record
Low Mood Visit Record keeps the baseline, recent fortnight and selected periods separate, then formats a short handover. It accepts up to five representative periods so the A4 sheet remains readable; this is a page-layout limit, not a clinical minimum or maximum. Use paper if that is easier, and bring additional notes whenever the short sheet leaves out relevant history.

Find and compare local appointment options
For a first discussion, look for a primary-care clinician/GP or a licensed mental-health clinician who assesses mood concerns. These searches do not verify availability, credentials or suitability.
Compare three to five real options yourself: verify professional registration, adult mood-assessment experience, appointment timing, fees/insurance and whether they can review a longer history. No provider names, ratings or rankings are supplied here.
Entries stay in the open page and disappear when it is refreshed or closed unless you export them. JSON can be imported later to continue editing, while CSV preserves the record in a familiar table format. Exported files contain personal health information, so keep them privately and share them only with people you choose.
What to hand over at the appointment
Give the clinician a brief account of your usual pattern, one or two better stretches, what changed recently and your main question. Include uncertain boundaries rather than removing them to make the summary shorter. The sheet is a conversation aid; a clinician may need the fuller notebook, a separate assessment or information about other causes.
| Part of the handover | Illustrative wording |
|---|---|
| Usual baseline | “I recall low mood most weeks since around the job change; the exact start is uncertain.” |
| Better stretches | “The holiday week was easier, but low energy continued; I cannot recall a fully symptom-free interval.” |
| Recent change | “This fortnight felt less difficult, although the longer pattern still concerns me.” |
| Main question | “Could we discuss the whole history as well as the last two weeks?” |
Bring a medicine list and relevant existing records if you have them, without changing a prescription to test the pattern. Mention periods of unusually high energy, markedly reduced need for sleep or other substantial changes instead of trying to fit every experience into a low-mood account. The history helps the clinician ask the right questions; it does not rule out another condition.
When to stop logging and get help
You do not need two years of notes, two months of improvement or a finished sheet before seeking care. If tracking makes you ruminate, repeatedly check yourself or feel worse, stop and explain that difficulty at the visit. A short verbal account or a few examples can still start the conversation, and worsening mood or function warrants prompt contact with a healthcare professional.
If you have thoughts of suicide or self-harm, seek support now rather than waiting to finish the log. In the United States, call or text 988 for crisis support; outside the United States, use your local crisis service. If you may act on those thoughts, have already harmed yourself or cannot stay safe, contact local emergency services or go to an emergency department immediately.
Questions about a long low-mood record
Does a good week mean the low mood has ended?
A good week is a real improvement to describe, but it cannot describe the surrounding months by itself. Note what changed, what remained difficult and whether the improvement continued. Let the clinician interpret its significance alongside the full history.
Can a PHQ-9 miss a long low mood?
The standard PHQ-9 focuses on the last two weeks and does not reconstruct a years-long course on its own. Answer it for that time window and bring your longer history alongside it. A recent low score does not settle every question about earlier symptoms, and the log does not establish a diagnosis.
Do I need two years of daily notes before the appointment?
No. Bring whatever observations and memories you have, with estimates and unknowns clearly marked. The adult diagnostic duration is not a requirement to delay care or create a two-year diary.
Is dysthymia the same label as persistent depressive disorder on a chart?
Dysthymia is an older term associated with what is now called persistent depressive disorder, although terminology and coding context can vary. A label does not show the complete timeline or explain why it was used in your record. Ask the clinician what it means in your own chart rather than using this sheet to change a code.
What if I cannot remember when it started?
Use your earliest reliable memory or a life-event anchor and write that the onset is uncertain. Keep known event dates separate from estimated mood dates. You do not need to supply an exact starting day to ask for an assessment.
Should I use this for a child’s irritable year?
This guide and record are designed for adult visit preparation. Children and adolescents have different assessment considerations, so speak with an appropriate clinician about what to record. Do not use the adult timeline or its wording to assess a child yourself.
Bring the pattern you can honestly describe
The most useful record separates a long-standing baseline from better stretches and recent changes while keeping uncertainty intact. It need not be complete, neat or diagnostic to help you explain the problem. Bring what you have, ask for help when you need it and let the appointment do the interpreting.
