Know your early warning signs: snapping at people, skipping meals, staying up too late. Catch them early.

Trouble shows up in behavior before it shows up as a feeling you can name. By the time you would call it overwhelmed, you have been short with people and going to bed at two for a week. The behaviors are earlier and more honest than anything you would say about yourself.

Write your own three down, the ones that actually happen rather than the ones that sound right. If you cannot see them, ask a sibling or a friend, who probably can. Then pick one small response for when two of them show up together.
