The reality is you have needed to go in patient to stay safe. The fact that age of 17 you have high blood pressure should be a wake up call for your Mom and if not it needs to be a huge issue for you..

I know your not thrilled about a group home, But how could it be worse ? At least you would receive treatment that would help you.

There is a good chance that reporting is going to result you needing to leave the home, at that point you would have a social worker that is going to get the services you need ... I would report it all and get help now , before its to late.

Advocate for yourself.

Stay safe
