Most of the time I feel bored and lonely when I'm by myself but I don't like to socialize with other people too much. When I do have something planned with someone, I then don't want to do what ever was planned and back out at the last moment. I break alot of promises this way all because I get scared or nervous for no real reason. What can I do to break out of this feeling?? Why do I feel lonely but I don't want to be around people?? Is this depression, anxiety or both? Please help...
