I started getting physical anxiety symptoms 4 weeks ago and I'm already tired of this discomfort I feel.

My symptoms are having to take deep breaths often since lack of oxygen, heart rate will sometimes beat faster than usual, sweaty palms, chest shaking when exhaling, feeling cold, 2 cases of derealization, a wave of an unusual feeling going up and past my stomach and chest which last 2 seconds which is enough to make me put down my phone to focus on my discomfort.

 I'm not diagnosed medically but these symptoms feel like anxiety based on my research, I'm fine mentally but physically I'm not since I'm getting these symptoms almost everyday towards the end of the day for some reason, anywhere from 9-11pm, I will last an hour or 2 with these symptoms and also happens when driving home, it starts off strong and starts coming down after some time has passed, and goes away when I get get home. But almost all the time my symptoms activate when I'm at work.

I've only ever had these symtoms at my house once or twice, the rest of those times it happened at my workplace, towards the final hours of my shift when nobody is bothering me, I'm all fine in my head and basically just chilling but that's when it happens to me, I've started using the breathing technique taking deep breaths and holding it and exhaling slowly, and it helps weaken my symptoms during those times but it doesn't fully get rid of it.

I've had it in the past when I was 12 and 13 without knowing what it was at the time and I haven't had for such a long time after that and it comes back and hits me again when I'm 22. 

Just writing this because it helps me not focus on my symptoms, watching videos doesn't give me that effect tho
