Think about this, how many people have actually died or not got well after getting their tonsils removed? I doubt a lot of people have died or not woke up or something. You're going to be perfectly fine. If you're worried about the actually operation, bring a stuffed animal, even if you're too old for that. I'm 14, and if I had to get sugery, I would be bringing a stuffed animal to hold on to. Or I would ask my mom to be there while they put me to sleep. Ask your hospital if you can have your mom there, or if you can bring something in the operating room. If not, I think by law you can have a nurse be by you while you are being put under. Listen to some relaxing music. Also, ask your doctor for a detailed explanation of what's gonna happen to you. Have trust in your doctor, he/she is there for your well being, and they didn't go to college and earn a degree for nothing! They know what they're doing!
