I identify by my anxiety

Whenever I want to do something social everyone laughs at me like it's hilarious and it makes me feel I need to stay in the way I am.
I think im really just an introvert. I think a lot of my anxiety is caused by me as a defense to not have to deal with people when I dont feel like it. And yeah I really do get anxious if I dont get to recover and have alone time after ive been social.

When I compare to other people with anxiety disorders I feel like a fraud. Many cant even work or wont do it. Ive had shit social skills my whole life but they have improved.
Ive done many things that arent typical for an anxiety disorder triggered very much by social situations...
-I talked a friend into singing karaoke with me at an event 3 years ago, and yes we were sober. I loved doing that.
-When I was a teenager I went to a concert where I met up with a random girl from the internet I had only texted once, and before the concert we spotted the singer with his bandmates at a restaurant and I talked her into walking up to them and socialize.
-In school, where I was bullied for always being quiet, I asked our music teacher to let me sing solo at a thing we were going to have and he allowed it. I was not nervous.
-2 years ago I studied at a distance with occasional meetings at the school. The first time I travelled there I was so social I kept jumping into conversations. The next meetup I was drained throughout though, so I withdrew the whole time. I was experiencing a low because I get those and I dont know why.

Based on many experiences of mine I wonder about my diagnosis of having a anxiety disorder. I feel more and more like I just fall into the role I have recieved of being "the anxious one". My therapist even said during our last session that she doesnt think I have social anxiety (which ive been diagnosed with) just general anxiety caused by having lacking social skills which has made me insecure. I think she may have got it right there. My social skills are improving a lot though and when im able to see that and feel confident my anxiety goes away immadiately without any work... At least until I get reminded somehow that im supposed to be anxious.
