How do you stop stage fright?

I'm going to play an open mic tonight. This is probably my 20th(or around that number) playing one, but the problem is I feel like I'm always having alot of anxiety and constant stage fright. How do you get over that?

Have you tried exercising at home? Maybe in front of the mirror? I think also finding some distractions before the "event" can be helpful. What about a therapist? Could that be helpful?

I have a great deal of catstrophic thinking - I suffer a lot in public. Things have gotten easier though. CBT work taught me a great deal and provided many coping skills. Although it's now been a year since the therapy I still do the homework when I can. I especially work on de-catastrophizing my defeatest thinking. There are numerous worksheets for this on the web.

Yeah, I have tried that a few times. Thanks I could try those

Just keep playing in front of the open microphone. Practice is what will help. You need more than 20 times.

How did it go?

I forgot to point out that no one remembers perfection and that mistakes are often recalled most fondly.
