Why am I feeling like this?

Why don't you pray and ask God to help you with your relationship with your Mother? God loves you and wants to help you with this and everything else. Congratulations on your piano playing! Keep playing and pursuing your pions in music - regardless of the approval of other people. Your at a very difficult stage in your life, but keep doing what is right and things will work out. Also, you probably know this, but don't contact anonymous people asking you to contact them, here on Y! or anywhere else online.
