Depends on the stress, if its just a tense situation I try to keep my eyes open, think about the events unfolding and the options available to deal with it, if there is a need to deal with the situation. If its anger related stress, I get a rush of energy and feel the need to get up and walk, this allows me to let the steam off. If it becomes too much to deal with, I tend to retreat back into myself, take as little place as possible, lie down if possible, my brain usually can’t stop thinking but doing something autonomously (doomscrolling or anything else) helps.
