social phobia

Hello I think I suffer from social phobia and discussing phobia. Whenever I'm around people of someone telling a speech I don't feel comfortable I feel my head getting tightened . Hard to get eye contact with teacher when he's giving a speech . I'm doing my best to get rid of this phobia . Any help or suggestions ?

i used to look behind them or on their forehead lol. they cant tell. also, the older i got, the more i realized that the one talking really isnt focused
on me. they focus on what they are saying.
relax and also when i listen to what they are saying, i didnt focus on the eye contact as much.

Thanks by the way for the answer
