I get it bud I used to be like you. Im 28 now, been in the military and now going to school for software engineering. I know it sucks, I truly do, but exposure therapy is the only way to get rid of the anxiety. It's like a muscle with anxiety. When you first start working out it's gonna suck and hurt. Eventually though, you get stronger and stronger and small then extremely tough workouts are doable and you always feel great after. It takes work though. It's a tough pill to swallow but we all had to take it to be better. Hope that helps. If you need to talk feel free to DM.
