I think you should go. So much easier said than done, and no doubt you'll have to face anxiety filled situations, but odds are you'll surprise yourself. I feel that way because you mentioned Dr. Thomas Richards "Overcoming Social Anxiety". Good stuff, I also listened to his audio tapes over a year ago now and it's helped a lot. I do take Clonazepam 2mg, so like you I still feel like I need a little extra help on top of the CBT.
Joining an SA group, which I wish I had access to here, is a great idea. You'll probably make friends there. People with SA are hard to find, but the ones I've come across are always really nice and non judgemental.
This past year was big for me. Last Sept I finally quit a low paying job I was basically hiding behind for a few years. I guess I just got too comfortable, mind you I still had some big struggles at times, but I really enjoyed some of the people I worked with. I think I was scared to leave something that was so hard for me to find, a place where I could for the most part be myself. The idea of College, presentations, campus life, not an option. Was always too scary of a thought, especially with my High School memories. But I've always had huge ambitions on being a cartoonist one day.
I honestly had no idea if I was ready, or how things would turn out but I was feeling better and decided it was go time. So I applied to an art school in a new city where I'd have to start all over, and make new friends. I even decided to live on campus knowing that if I isolated myself in an apartment off campus, it'd just be that much harder. But yeah, overall, a really good year. I've always been the type to only have one on one friends, always too shy to speak up in a group of people. But there I was, fairly talkative (at least for me) at the caf, and ended up getting very close to my first ever real group of friends. Presentations weren’t easy but I practiced a lot the night before, I’ll admit I’d pop two pills instead of one on the day, ha, but they went pretty well. CBT helped me not obsess over them like I used to and I moved right along. Art’s a field that’s so competitive and hard to get a stable career in, but I feel like I’m at least not going to be stopped by SA. I’m good to go elsewhere once I graduate next year.
Everyone’s different, even though everyone on here can relate so well with one another, I still feel like it’s very unique in how it affects all of us. There’s no way anything anyone writes on here is going to let you know how things will go. But it’s your passion, you’ve done CBT, and you have a little extra help with meds. The same combination that worked for me.
Best of luck with whatever you do.
