There are many people that feel this way; I often do too. I've realized though that it is better to have a few close friends that you know you can depend on, rather than having a lot of "so called friends" that you can't trust. Good friends are very hard to find, but eventually, you'll find the person/people you click with. Don't let the past get in the way of your new relationships with people. To make truly good friends, you have to learn to trust them. It's difficult to make friends if you don't socialize a lot, so maybe attending some social events would help you out a little bit. I wish the best to you
