what do I do

I have depression and im on an anti-depressant and im only 13. My mom never listens to me and she takes the things that makes me happy away from me and she says "im just doing what's best for you" But your not helping me but taking away things from me that make me happy. I go to group therapy, I have a therapist that comes to my school every Thursdays and talks to me. I've been to a hospital to get help but yet I still feel depressed. Some of my depression is greif. My papaw Ron which was my best friend passed away last year in May. Well we never had a memorial or a service, he was cremated. The last time I saw him was laying in a hospital bed suffering from death and pain. Does anyone know how to help me??
