It's possible it's related to the disorder you mentioned; it's hard to say for sure, and I'm certainly not in a position to diagnose. What I do know, however, is that it's pretty difficult for most people to have anyone in their immediate space, getting into their stuff. So I would maybe just try not to be so hard on yourself about it. It sounds like you are going through a lot already.
In the meantime, it might be a good idea to check out the AVP forum, as atomicc mentioned. Welcome to PC.
