Does this sound like I have attachment/distrust issues? (Please help, this is long?)?

I think that you have never gotten all the way over your childhood experiences, when the very people you should be able to trust were not there for you, so You walled yourself in so you would never have to trust anyone.Now you've built up your defenses again. I think you should make yourself talk to people, and realize that not everyone will hurt you and there are many trustworthy people.
