HI toomuch.
Most people have some degree of social anxiety. It keeps them from being the obnoxious ones in the group.
But why should you have to wrestle with this problem to such a degree? I think you should speak to a professional about this. While it is normal to be a teenager who has social anxiety to some degree, it should not prohibit you from participating in things.
Also, I want to comment, that you must be very intelligent. Dense people dont get social anxiety. I hope you can learn to channel your great insights and awareness away from if you are seen as “good enough”, to just going to have the fun you have a right to have.
Please try to nip this while you are still young. You have a life to live and fun experiences to have!

Hatzlacha!
