Is this for me?

I just don't know if I am ever going to feel good about doing instrumentation. I keep thinking I will get better but I am not. I just don't feel very comfortable. I am so afraid to hurt someone that I feel like I am not practicing right. Added to that, I am so tired I fall asleep in class all the time. Maybe that is why I can't sleep at night, or maybe it is the stress of building a house and going to school and all the other BS. I just wish I was fabulous at it right now.
