Have I ever told you I'm an unstable insecure control freak who regrets most decisions I make regarding my relationship?
Wow, that's quite a revelation!
I'm very angry since most of my friends turned into something I don't like.
Well, you're willing to admit to your faults, so that's good. Now recognize them for what they are and work on them for your benefit.
This is easier said than done.
Yes, but you've already taken a big step. You should be proud of yourself. You could greatly benefit from counseling.
