What might a person do in reaction to a panic attack/their symptoms?!

honestly i tend to get very edgy, my OCD acts up a little and i'll move around a little/re-arrange things to try to keep myself calm. i don't cry or yell, because i know exactly what it is...i know it's a panic attack so if i'm around other people i mostly just try to breathe, count, whatever to keep myself calm. i don't alert anyone to the issue, i just try to ride it out.

when i'm alone i just write, or do something to try to take the focus away from the panic attack...still i don't really cry or yell or run or anything.

whether i'm by myself or alone i'll usually have a cigarette or drink some water if either is a possibility.

it can be overwhelming, but i like to try to maintain my self control. i've seen other people react very differently to panic attacks (crying, freaking out, etc.), but i personally can at least somewhat fake calmness even if i'm completely falling apart (only my gf can tell, but she's learned that i prefer if she ignores it.)

edit: btw i can only speak through personal experience, but for the most part regardless of what my panic attacks are caused by (or whether or not i'm sober) my reaction is pretty much the same. the only time i've ever had a panic attack where i completely lost it was once after smoking "dusted" weed.
