That's only half the diagnosis. You're forgetting about the requirements to have a PD.

It's a question of degrees. AvPD is one of the hardest to self diagnose because people just don't have the distance to really see how much it's affecting them. They always overestimate. Everyone has avoidant traits at some point in their life. If you can't function - it's not that you're poorly functioning, you're incapable - due to your feelings of unworthiness and fear of being judged, that's AvPD.

The other thing is that it's getting worse for you instead of better. Avoidance doesn't get worse. It peaks in the early 20's and then it stabilizes. It also doesn't get better. Once you have it, you have it. It never goes away.

There is also no reason for your feelings of inadequacy if you're avoidant. If you're doing something that you're ashamed of, then you're just ashamed of yourself, not avoidant. If you would judge everyone else you run into the same way you judge yourself, then you're just ashamed (regardless of whether it is justified or not). If you would not judge someone else in exactly the same situation you're in as much as you do yourself, that's avoidance. And I'm not talking a little bit, like thinking 'I should have known better.' I mean making standards for yourself that are so high no one on earth could ever reach them, and not even dreaming that anyone else would be expected to do it. It's a higher standard than even perfectionism. Even if you're absolutely perfect, it's still not good enough - that's avoidance.

I'm not saying you don't have a lot of things going on in your life. I'm just saying, it's an absolute waste of time to research something without seeking professional advice, especially when there is no effective treatment or cure. If you've been in therapy, unless you've been working with incompetents, they would have noticed it by now. You're distracting yourself by skimming through websites and picking out a label. You wouldn't believe it if you went on webmd and saw you had the symptoms of a super rare brain disorder, would you? If you were serious about believing you had AvPD, then you would go to a psych to get an actual diagnosis.

I sincerely hope you don't have it. It's incurable. Basically there's no hope. I hope you go and get a diagnosis with an actual treatment and you feel a whole lot better once you've put in a few year's work.
