How do you feel when you get stressed/anxious?

when i get anxious, i feel like i can’t breathe. it feels like there is weight on my lungs that prevents me from taking full, deep breaths. it also feels like someone is clutching my heart in their fist and won’t allow it to beat fully. sometimes i get an urge to punch something, or just freak out physically in some way. how about you guys? i don’t know if these feelings are normal
