I miss so many chances...

There’s times when I have the chance to do something fun with other but I get so worked up and tell me self “what if they don’t like you, what if they think you’re weird, what if you’re too boring” and I freak myself out over it and make an excuse not to go. I really want to make more friends and have more connections with people but it’s hard for me to just be myself without the fear of others judging.

And advise to over come this?
