How do I stop performance anxiety when you have severe anxiety disorder? For example, i'm a avid chess player and I love playing chess. Sadly when I play tourneys sometimes I get so nervous for no reason making me lose most games out of sheer anxiety. Sure, your suppose to get nervous before something big. Who doesn't? But when your shaking, having trouble breathing, sweating like its 50 degrees then something is definitely wrong. This always happened to me in tests, stage performances, presentations... Its so frustrating. 

I've found nothing that helps me cope... Breathing techniques wont work, medications look like they cause more harm than good, talking to someone doesn't help... Are there any things you guys do/recommend that can combat this?
