I think you should consider a therapist or counseling for the anxiety and panic. You might need to start with some meds to help you feel better. As for the shaking......... my mother had it and two of my sisters have it. They were tested for Parkinson's but don't have that. The doctors say they don't really know the cause of the tremors but some people just have them. Never mind what people say. I know how it must hurt but it just shows their ignorance. If they make fun of you then take the opportunity to educate them on the problem and maybe you will help yourself and anyone else they might meet who also has the problem.
