If your peace depends on everyone else behaving, that’s a lot of people you’re counting on.

Depending on the right conditions is a bet on other people, and there are a lot of them. Your brother has to be in a decent mood, the group chat has to stay calm, that one person has to not post anything. Any single one of them can undo your afternoon, and none of them ever agreed to the arrangement.

Look for the parts of feeling steady that do not need anyone’s cooperation: sleep, food, moving your body, an hour that belongs to you. Build on those first. People will still get to you sometimes, but there is a difference between being knocked sideways and having no floor.
