So im a musician that has to peform a lot. But i also have really bad anxiety, particularly social anxiety. Ive got quite a major music exam this month and im worried my perfomance will be affected by my anxiety. I had a music lesson the other day and i found  myself getting extremely panicky when my teacher was 'assessing' me. Its never really happened before but i remember just shaking really bad all of a sudden. My bottom lip was quivering so much that i couldnt blow any air out. My eyes were also watering and i had problems with my breathing. I definately dont want this to happen in my actual exam so im looking towards anxiety medication. Ive never taken it before so i dont know what to expect. Also would i be too young to take it? 
Advice and personal experiences would be much appreciated :)
