Hi there momitygov, I can speak from experience as I'd been in the same boat as you in my 20s. At 23, I didn't even know what was wrong with me and I'd freeze when trying to hold a conversation with more than 1 person. For a long time, I had simply surrendered to being the way I was until i started to learn about this condition and how screwed-up-socialization at a young age causes distorted perceptions of yourself, people in general and all sorts of issues in dealing with people at a later stage. What I'd invite you to do is to think back to your childhood and recollect abnormal/unpleasant experiences with people close to you. If you're having difficulty figuring out what was abnormal, talk about it with people you're to. Once you've figured this out, try to let it go by exposing yourself gradually to social situations. 'Gradually' is the keyword here, you have to make sure that it doesn't get overwhelming to start with. Once you become comfortable with one person, increase to two and so on.

I'm 32 now and have to a large extent overcome my once crippling social anxiety by using gradually increasing exposure. Know that you have worth just by being here and trying to be better. You'll struggle initially but as long as you're making incremental progress, you're on the right track. And kudos for going out and facing the world. I wish you my best!!
