Handling overwhelming emotions?

Hey everyone here 👋

I've been wondering: how do you handle cases, when you get overwhelmed with emotions to the state, that you simply cannot focus on anything but that emotion? I hate that feeling, because it really makes me to feel sick with just being emotional.

My take is that I usually just break from a situation, take an hour or two, and try to stim myself with something else: a game, a movie, something like that. Though, sometimes I don't have a time space to do it: I need to be gathered and focused here and now, with no space for wiggling.
