Re: what the diffrence between Shyness and Social Anxiety
I suffer from extreme social anxiety. When put in a social situation (even with people I know), my heart will race and I constantly review and review over everything I say to make sure I don't say anything wrong. I've even had bouts of anxiety attacks including hyperventilation, heart arrythmias, nausea, and even fainting.
Although my symptoms are severe, milder symptoms can also be Social anxiety...like JB said, the symptoms can vary a lot. What you are talking about sounds a little more like you are having anxiety over the bullying you are facing. You should probably consider speaking to a teacher or principal about the bullying and see what might be able to be done.
Other than that, make sure you talk to your parents, they might be able to help you. Just having someone to talk to can help a lot.
As far as a diagnosis, I am not a doctor, I can only offer you my advice.
