What physical symptoms of anxiety do you guys experience?

For me I get stomach issues when im anxious. I normally get nausous, have stomach cramps, and lose my appetite. During the first few months of every school semester I always, and I mean always have to poop right before I leave class. which makes me more nervous because I feel like im gonna be late or that the scent will follow me. I try to go 10 or 20 minutes before but nothing happens. I swear my body just hates me.

So, anyone else get physical anxiety symptoms?
