answer:Have people told you you look like you are going to cry? Or, that is what you think? I say practice smiling and fake it til you make it. I know it is very difficult, anxiety has to be one of the worst things to suffer from. The feeling of lack of control is awful. Just look at school as being a performance. The curtain goes up, and you present to the world your calm and happy self. Stand up straight, walk confidently. Eventually you might begin to feel calmer and happier. Behavioral Cognitive therapy is known to be effective for people, and basically it reinforces facing fears and moving forward through the anxiety. I do think the more you avoid things, the worse your anxiety will get, I know that seems counterintuitive. Also, there might be something seemingly unrelated to the social anxiety that is at the root of all this. Something in childhood or your family or a specific event that happened that causes you to be anxious. Dealing with that might relieve you of the general anxiety you feel. Did someone once comment on your facial expressions and it hurt your feelings badly and it sticks woth you? I recommend also taking a class like karate or dance or swimming or some sort of sport that will give you strength and awareness of your body. Something you enjoy.
