I have a somewhat uncommon problem so it seems?

Your in 11th grade so why dont you get a part time job and pay for the lessons yourself. My daughter is the same way, she wants lessons for everything but loses interest real quick so we hate the thought of spending money on something she wont stick w/. But we do it so she can try, If you pay for lessons yourself then your p;arents will see that you are very serious about it:)
