I was told I have Avpd and I’m also in the uk. Grrrrrrr. I suggest doing as much of your own research as possible. Misdiagnosis isn’t uncommon over here
I had some sort of CBT which didn’t help. It was more like bulldozer therapy though to be honest
If you have a good therapist, they can help. But if the therapy is time limited especially there is the issue of wanting to “please” the therapist and to tell them they are helping even if they aren’t
Avpd is more “all encompassing” than social anxiety.
I now feel like deleting this post ..
