What cause anxiety or panic attacks??

So I’ve been diagnosed with anxiety (very bad anxiety at that) but usually it comes randomly, then it’ll eventually go away for about a year. Then come back again.

So my anxiety just came back. I’m not in school which was the cause of my anxiety and I’m not doing anything to make me nervous or anything I’m legit anxious for no damn reason.

Then I have these anxiety attacks that lately have been leading to panic attacks. Now I’m thinking I might just have a panic disorder because of how frequent they are getting. Sometimes I get the multiple times a day. I’m going to be going to a doc ab it though.

So anyways I’ll just randomly get them at night usually. Just night I got one while driving my car like wtffff.

I get dizzy and sometimes light headed. I feel like I have trouble breathing but I’m reality I’m able to breathe just fine. And I start to get really scared that I usually cry. Can someone help. I’m ab to go into the damn movies with my friends but tbh I just want to go home rn. Fuck idk how I’m gonna keep calm the next 3-4 hours.
