Anxiety about school and life

[fantasticamy]

I am getting bursts of anxiety and I don't know what to do about it! I am so worried that I will not make good enough decisions for my life and especially making mistakes in my decisions. Everyone says making mistakes is okay, but it really isn't sometimes. I have no idea whether I should go to a prestigious school or stay at the one I am at, and I do not know what classes I should take, I am afraid of not doing well on exams, and I am afraid of being incompetent at piano. I feel like I cannot do anything to control my life and future, help??
