Sorry there is no way to get rid of AvPD... it's personality!

But before you sink your head into your hands... AvPD is controllable....most of the time!!

Now plan A. would be to first get diagnosed rather than have all your thoughts pull you down on a assumption.
(bear in mind having Avoidant traits doesn't make you an AvPD)

I have been diagnosed with AvPD and I have told a few people, and maybe getting professional help will do you as it does to me.
A few people know and it's not a issue if I attend a party for 7 minutes and quickly leave, they just know it's what I do and they take no offence and I don't beat myself up over it.

Get yourself some help and when your ready let those people close to you know what's been going on and then there's no pressure if you behave accordling to your internal feelings.
