Since yesterday I’ve been having trouble with my breathing. I exercised a little bit and since I’ve become conscious of my breathing to the point where I can’t breathe unless I’m doing it manually. I tried distracting myself but nothing worked. I couldn’t fall asleep until around 6 AM because when I stopped manually breathing I couldn’t breathe. It’s continued into the daytime and it’s now followed by a tightening of my chest and a sore throat. It’s subsided for a couple minutes when I forgot about it but you can’t tell yourself to not think about something, so how do I stop thinking about breathing??
