My abandonment issues come from being adopted and from being raised in a very dysfunctional family as well. I think your issues (especially shame) might come from your childhood too. If you have a tendency not to be polite or correct...deliberately catch yourself in the act and change it. I had to do that with my anger problem. That was hard. I'm glad you're working on your issues. You'll soon be making friends that you bond with. Best wishes.
