Anxiety. It's very draining.

I want to be more open and outgoing to make more friends, but my anxiety always holds me back. Basically, I constantly worry what other people will think of me, and I'm afraid of doing something stupid that I'll regret. So, I tend to keep to myself. That's probably a large reason why I don't have friends anymore. I went from having a large handful of friends to having none. I tend to shut everyone out when I'm anxious.
