I Have Anxiety Attacks

this weekend I was with my brother and he decided to go to bowling ally. all his friends were there, I didn't know them but we got our lane and I didn't expect their ti ne so many people. they took their turns snd it eventually was mine I went up there held onto my ball and then it happened. my brother came up to me and took me outside to calm me down and I went back to normal and he asked if I wanted to go home but I said no I'd just stay outside while he had fun with his fried so I did for a couple hours
