Finally getting better and my mom is taking away my Prozac, what should I do?

For context I am a 17 yr old male in 3rd year high school. I’ve struggled w severe mental health issues all of high school and middle school(Gad, MDD, and SAD). I recently decided to not come to my moms for one night and stay at my dads and she said because I did that she’s not getting my next bottle of Prozac. After two months of taking it, I’m finally starting to feel okay. Not wanting to self delete and a lot less socially anxious. I’m finally able to socialize with my peers! Anyways I will hit another major depressive episode soon if I get off of this Prozac and my life will be horrible again and I don’t know if I’ll cut myself or not as I got very close to that my last depressive episode. I view her actions as abuse. My dad is unlikely to continue my medication as my mom did it behind his back.

What should I do?
