How wonderful that you know you can do it--all these grand things waiting for you! I'm jealous!
I love street fests and outdoor concerts. Sometimes I will get triggered, though, with the noise. But I do my best to "prepare" myself for it. It's a trade off for me. Enjoy myself and don't worry about getting triggered or stay at home and mope because I'm bored.
It usually works out that I go and have fun...
