HI and welcome!

I have social anxiety, too. Mine has gotten WAY better as I've gotten older. I am definitely afraid of approaching people, though. The scariest thing is to ask a manager for a job application. I am also afraid to talk to people when I'm out with my friends...to people that I don't know but I'm being introduced to...I'm always very awkward in those situations. I often avoid eye contact with people because it makes me uncomfortable. I am very anxious about making ANY phone calls. I just hate it.

My fear is of being judged or rejected or of embarrassing myself. So it's a bit different from yours.

But with all social anxieties, the best thing to do is continue to expose yourself to unpleasant situations. The more you do it, the easier it becomes. Do you have a therapist? Maybe they can do exposure therapy with you.
