[HELP] Father insists I'm a heroin addict

So I'm a T1 diabetic on MDI, I have poor control and my father isn't helping.

He keeps throwing away my syringes, test kits, insulin, etc. claiming that it makes his house look like a drug den and that only heroin addicts need needles.

He goes through my stuff every day while I'm at school/work. I am not allowed any degree of privacy even though I am in my mid 20's. Everything I own is "actually his", I'm not allowed to say no or disagree in any way, half the time I'm told not to speak unless spoken to, he controls everything, right down to when/what I'm allowed to eat, wear, and sleep. It is most definitely a /r/raisedbynarcissists scenario.

I cannot afford to move out and am losing money as is just trying to make basic COL standards. I have tried applying for various social services but do not qualify because I live with my father, but again at the same time I cannot afford to move out.

I have no other family or friends to stay with. I'm at a loss for what to do.
