Hi! Social anxiety is one of my dearest friends when I'm around people. I think it stems from the fact that my father was punishing or yelling at me me whenever I spoke. I believe I mentioned this before. Anyway once I tried to conquer it by reading this
book. I found it interesting, but apparently I wasn't motivated enough to apply the techniques. Maybe it will be of more benefit to you. I believe you can find it in any public library if you don't want to buy it.
I hope you can find your own way to cope with this. Good luck
