Year-end mood review: looking back without spiraling

A year of mood data can answer questions a single month cannot. It can also pull you into hours of looking back at your worst stretches with no plan for what to do with them. The version of this exercise that helps stays structured, time-boxed, and forward-looking.

Before you start

Two ground rules that prevent the review from becoming a spiral:

Time-box it. Forty-five minutes maximum. Set a timer.
Have a next step planned. Decide before you open the app what you are going to do with what you find: a discussion with your clinician, a change you want to try, a question to bring to your next visit.

If neither rule is in place, postpone the review until they are.

What to look at

The four passes through the year that produce the most signal in the least time.

1. The shape of the year, at a glance. Open the calendar view. Skim it from January to December. Note: where are the runs of color? When were the long good stretches? When were the long hard ones?

2. The cluster of hard months. Pick out two or three of the harder windows. For each, ask:

How long did it last?
What was happening in your life that month?
What was sleep doing?
What were medications doing?

Ambulatory data is well-suited to retrospective pattern review precisely because the entries were made in the moment2013; they are not corrupted by the way you remember the year now.

3. The cluster of good months. This is the one most people skip. The good months contain as much information as the hard ones: what was going right, what habits were in place, what your sleep was doing.

4. The recurring pattern. Is there a season, a month, an anniversary that shows up consistently? Sleep changes are often a leading indicator2008; does sleep drift line up with the same windows year over year?

What to write down

Keep the output short. A single page is enough. Aim for these five lines:

The hardest stretch this year was: ___
The best stretch this year was: ___
The recurring pattern I noticed is: ___
The thing I want to try differently next year is: ___
The question I want to bring to my next clinician visit is: ___

That page is what makes the review useful. Without it, you have just spent forty-five minutes scrolling.

What to skip

Reading every single note. The point is the shape, not the detail.
Rating the year overall. "Was it a good year?" flattens what mood tracking is for. Some months were hard; some months were good; both are real.
Comparing to last year emotionally. Compare data points (sleep average, episode count) if useful; do not compare your felt sense of two years.
Doing this alone if you usually don't. If you are in therapy, this can be a session topic, and is often more useful that way.

When to stop the review

If at any point you notice rumination starting (re-reading the same hard week three times, getting pulled into the worst day), stop. Close the app. The review is not the place to process; it is the place to summarize.

What to do with the page

Bring it to your next clinician appointment
Use it as the input for a treatment-plan check-in
Hold onto it for next year's review; comparing two years of summary pages is a much better signal than comparing the years themselves

A note on what this is

This is not a self-administered therapy session. It is a structured review of data, less involved than a year-end retrospective with a therapist and more deliberate than skipping the exercise altogether. The point is forward-looking: what do you want next year to look different.
