I guess I'm dealing with something similar now--my belief that if I'm open and honest with people about my thoughts and feelings, they'll abandon/reject me. I'm in a place where I can be honest with people, but then I need reassurance from them that they aren't going anywhere. Repeated reassurance. The issue is, if people (in this case, specifically my T and marriage counselor) keep giving me that reassurance, then I'll never learn to trust that other people aren't going anywhere (or if they do abandon me, that they weren't worth having around).
