Why do i worry about everything when i'm around people and get extremely embarrassed over everything?

Social anxiety....: You sound like you are experiencing social anxiety. It might be helpful for you to be evaluated by a therapist who treats people with anxiety disorders; cognitive behavioral therapy would be a good first treatment to try, maybe before even trying any medication. The therapist could tell you if you should go ahead and try medication together with cbt, which often has the best results. Good luck!
