I see. So - you listed two reasons for not calling the CPS:

1) you do not want to get her in trouble
2) you are afraid of ending up in a group home.

So she threatens you with the police a lot. I think this, on top of everything else, excuses you and you do not need to care about (1).

(2) is a serious issue, but if the court overrides her and allows you to be on medication, does it necessarily mean that you would be sent to a group home? If you explain that you are not in physical danger at home and the only intervention you need is overriding her refusal to consent, would you still be sent to a group home. Do you know the answer to this?
