# ADHD bad day and can't function? Start with the floor

> Why capacity swings come with ADHD, what helps on a shutdown day, and how Donna sizes the day down to match.

**On an ADHD bad day when you can't function, lower the floor: pick one small thing to do, or decide to do nothing.** Choose the single easiest thing in reach (send one text, drink one glass of water, open one doc and close it again), or take the day off on purpose. Either one is a complete answer for a low-capacity day. ADHD capacity swings, sometimes hour to hour, and on the low end there is little left to spend. A bad day calls for a plan you can run at the capacity you have that day.

## Why nothing gets done on a low-energy day

ADHD shutdown days have specific mechanics behind them. Several tend to be true at once:

* **Capacity is a moving target.** ADHD comes with swings in energy and focus you do not control. A plan built for yesterday's capacity does not fit today's lower one, and forcing it drains what little is available.
* **Reward feels out of reach.** An ADHD brain leans on interest, novelty, urgency, and challenge to get moving. On a flat day none of those are firing, so there is nothing to push off of.
* **Starting costs more.** Task initiation is already the hard part of ADHD. On a low-energy day the cost of starting anything climbs, and a long list of expectations raises it further.
* **Stress compounds it.** A quiet day often brings more self-criticism, and research on procrastination ties that mood to further delay rather than less ([Sirois and Pychyl, 2013](https://doi.org/10.1111/spc3.12011)). A separate study found that easing up on yourself after a stall predicts less procrastination next time ([Wohl, Pychyl and Bennett, 2010](https://doi.org/10.1016/j.paid.2010.01.029)).

For the everyday version of getting unstuck, not only hard days, see [starting a task when you're stuck](/docs/guides/starting-when-stuck).

## What actually helps on a shutdown day

<Steps>
  <Step title="Name the kind of day it is">
    Say it plainly: this is a low day. Naming it drops the expectation from a full day to the day you actually have.
  </Step>

  <Step title="Set the floor at one small thing, or nothing">
    Pick the single easiest thing in reach, small enough that it sounds like it barely counts. One text. One glass of water. One doc opened. Or decide the day is a rest day, on purpose. Both are complete answers.
  </Step>

  <Step title="Make the one thing physical and tiny">
    If you pick a thing, make it a physical motion. "Open the doc" beats "figure out the report." A physical first move is easier to start than a mental one on a low day. This is a [small first Action](/docs/daily/working-an-action) shrunk further.
  </Step>

  <Step title="Let the floor be the whole day">
    One small thing completes a low day. Choosing to rest is also a decision, and it does not create a debt you owe tomorrow.
  </Step>
</Steps>

<Tip>
  Doing one small thing does not obligate you to a second. On a low day the floor is the whole day, and stopping there is complete. Measure against the day you are having.
</Tip>

## How Donna helps on a bad day

Donna adjusts to the state you are in: it reads whether you are running low, in the groove, or wound up, and changes what it asks, how it talks, and whether it reaches out at all.

* **A bad-day floor.** When you tell Donna it is a rough one, the interaction can shrink to a single line: `rough one. one thing or nothing, your call.` There is no prompt to produce more, and choosing nothing ends the exchange there.
* **One Action, sized to now.** Instead of a list, Donna puts a single [Action](/docs/concepts/actions) in front of you, sized to your current energy and anchored in a concrete first move. On a low day that move gets smaller, and you can shrink it further with the first-step handle. "Open the doc, five minutes" is a complete Action.
* **No scoreboard.** Donna keeps no streaks and counts nothing you did not get to. A quiet day leaves nothing to fall behind on.
* **Nothing waiting when you return.** If you stop for a day or a month, Donna starts from the current day when you come back. There is no catch-up pile and no summary of the gap.

When you start an Action, Donna opens the work view: a count-up timer and a writing space, with Donna available if you stall.

## Frequently asked questions

<AccordionGroup>
  <Accordion title="What should I do on an ADHD bad day when I can't function?">
    Lower the floor. On an ADHD bad day you do not owe a full day. Pick the single easiest thing in reach (one text, one glass of water, one doc opened), or take the day off on purpose. Both are complete answers. Make the one thing a physical motion, since a physical first move is easier to start on a low-energy day.
  </Accordion>

  <Accordion title="Why does nothing get done on a low-energy ADHD day?">
    ADHD capacity swings in ways you do not control, sometimes hour to hour. An ADHD brain leans on interest, novelty, urgency, and challenge, and on a flat day none of those are firing, so there is nothing to push off of. At the same time, the cost of starting anything climbs, and a long list of expectations raises it further. It is a fuel and starting-cost problem.
  </Accordion>

  <Accordion title="Is doing just one small thing actually enough on a bad day?">
    Yes. One small thing is a complete result on a low-capacity day, and so is resting. Measure the day against the capacity you actually have. Choosing to rest does not create a backlog to make up later.
  </Accordion>

  <Accordion title="What happens if I disappear for days or weeks and then come back?">
    Donna starts from the current day when you return. There is no catch-up pile, no summary of the gap, and no penalty. Donna keeps no scoreboard and does not reference how long you were away.
  </Accordion>

  <Accordion title="How is Donna different from a regular to-do list on a bad day?">
    On a bad day, Donna reads that you are running low and shrinks the interaction to match, down to a single line on the hardest days. It hands you one Action sized to your current energy instead of a full list, keeps no streaks or counts, and starts from the current day whenever you return after a gap. A standard to-do list asks the same upkeep regardless of how you feel.
