I guess you need to work out what you want out of your music. To me, it is an honour to be asked to play places as you have been. Why do you get anxious? Maybe if you think around that ... you could overcome it.

Sure you could stick in a safe place, and only play randomly when it feels 'comfortable'. But WOW you are obviously good at what you do, and (just in my opinion) it's a bit of a copout to do what you just did. Sometimes you just have to force yourself to do things and then what do you know, you've done it, and next time is a bit easier.

I've never been really confident about speaking in front of groups of people. I've been good at it when I have had to do it. But from forcing myself to do it - now it is something i LOVE to have the opportunity to do. And when you overcome anxiety/fear around a certain thing, you a) conquer that thing and b) it makes you feel better about yourself in general.

i don't mean this to be an unsupportive post so please don't take it as such. i hope you sort things out
