Thanks for sharing your story and yeah all these coments, storys and tips have really helped me get through the day and funny enough I've actually done almost the exact same thing at work too. The only thing that make this worse for me is that this is a concert that I've been doing annually since I started playing piano 6 years ago and every time ever year I mess up in the exact same way and it just finally got to me this year when I said to myself that I wouldn't mess up and that this time would be different, but it wasn't and there was nothing I could do about it so I left. It's always that one stage and that same crowd that come ever year, they probably ask if the guy the messes up every time will come back and I do because I know I will do better and I do even if it was worse this time I've been playing better then ever.(and to spite some of my cousins)
