I Have Social Anxiety

I would really like to make more friends and attend social events, but so many thought come to mind. What if the person I select as a friend is dangerous or weird? What if they annoy to the point were I have to severe the friendship? What if we can't partake in similar activities because we don't have simile interest? Do I attract weird people because I'm weird myself? Is that why I don't have friends?

It's not like I don't know how to hang loss and have fun and I know what social events I like and what my type of fun is. But my issue lies in communication; maintaining friends and relationships, and trusting people enough to be my true self and not guarded. I guess the only solution is to continue being alone.
