Hi Music Lover,
Welcome to the forum!
This is a difficult situation, and is unfortunately a quite common one. I'd like to draw your attention to a website and a previous beyond blue thread. Keep in mind that the posts from previous forum threads are from people with unique situations which will not resemble exactly what you're going through, but could still help in some way. It's good to read how others deal with family conflict.
I hope this forum is a supportive place for you, and that others reply too :)
