I dont knoe what to do. I really want to...?

[Alli S]

I really want to play guitar. There is this band with amazing guitar players and they are really inspiring me to start. I have been playing the piano for 5 years so I know how music works. I told my mom that I wanna teach myself and she said "No. Its to hard. u will never be able to learn it." even though she has never played it. And she said that I could quit piano and take guitar lessons but I said no. I love piano to much to quit now. And my family is a fairly wealthy family. So money isnt an issue. My mom doesn't believe that you can do anything you put your mind to. Please help. What do I do?? I really wanna play guitar
