Hi, I'm A 20 Year Old Male And I've Been

Hi, i'm a 20 year old male and i've been recently experiencing what I believe to be hot flashes at night, and now as im typing this, earlier than usual. I am also focusing a lot on my breathing and if I don't think about my breathing i'll start heating up again and get anxious. I have a fear that my heart will stop if I don't think about breathing and i'm just looking for someone to talk to about this and get an opinion. Thank you.
