I think for me now, my shyness has surpassed my social anxiety. I do believe both are associated with one another but are also independently different. It used to be that both where very very strong and I would just be such a wreck in social situations. I would be so anxious and nervous and then just as soon as someone spoke to me then my shyness would kick in at 7,000 RPMs.
These days my social anxiety has gone down significantly, and I mean a whole lot from what it used to be. My main problem now is my shyness, I still can not go up to talk to people and mainly women. I work in a grocery store, and my co-worker who is one of my friends just got hired and he is so much more "alive" than me. He talks to customers more and is fast to tell them "good afternoon, is there anything I can help you with?". He has greeted more customers in one week than I have in the 8 months I have been there, and I am honestly not exaggerating one bit.
I get so shy and blank when attractive women speak to me. I blush whenever I am caught with beautiful women talking to me for whatever reason. Damn it, I really hate it. Oh and I was also voted most shy in 8th grade as well...I was annoyed that they would put me in the spotlight like that. Like being voted most shy would help me get better or feel better...it's like being voted the most stupid or most ugly if there was such an award. It's insulting and unnecessary.
