I've been dx'd w/Personality Disorder NOS (not otherwise specified) w/avoidant features. Most of the time, I feel like I'm fighting for my life as I desperately want close relationships, but my defenses head off any success I might have. There are people who don't care about having relationships and those, like me, who do. Both can be dx'd with Avoidant Personality Disorder. Not to discourage you or sound like it's all doom and gloom, Avoidant Personality Disorder is very difficult to treat. Does your T think s/he can help? Do you care about having relationships? If not, there's nothing wrong with that lifestyle, but it would dictate how your therapy is structured.

There's a forum on PsychCentral for Avoidant Personality Disorder - as well as other PDs. You might find interesting information there. Best wishes.
