You hang in there sweetheart!! You've come so far and are doing so good. It's not a surprise you are overwhelmed. Think to the positive of how far you have come. You've got exactly the right thoughts on the alto part--it shows your range, that you are willing to step out of your comfort zone and do it--and do it well. You've been writing songs since 14 or younger--theory should be a piece of cake, just concentrate on what you know and apply it. Take one class at a time. When you start thinking of all you have and the tasks that are due, you'll get overwhelmed. Handle them as they come. Talking with your tutor is the best way....maybe once she knows all what is going on with you, she'll allow you to do the songs you'd like....but remember her goal is to challenge you, to make you reach higher than what you already are. Have faith, sweety. I believe in you.
