The more you perform, the less anxious you will be. One thing to always remember when performing is, that you are NOT trying to impress an audience, you are NOT doing something to be nervous or anxious about. What you are doing is, you are completely immersing yourself in the music, you aren't thinking about the audience, you aren't thinking about yourself, but you are thinking about the music. If you do this, you will enjoy performing, and your performances will be stunning.
This is certainly easier said than done, but keep it in mind and think about this when you decide to perform next. It makes all the difference in the world.
