How do i get help for a family member who I suspect is depressed? He is not sleeping, smoking and drinking coffee e nonstop, always have bleak outlook and negative thoughts about life. Talked about hurting his children.

He doesn't want to go to a doctor for a medical check up, last time he went was a decade ago, he stopped taking his meds after 1 week saying the meds is making him crazy.  Now he refused to even leave the house.

The local physiatrist hospital told us to get an MO to issue a letter before they can have a look at him. How can we do so when he gets angry when we suggests to take him for medical check up at general clinics?

He keeps insisitng he is not crazy and that he doesn't need help and yes.. delusions that someone is out to get him. His actions are worrying - he can stare into space for hours then go to the extreme- angry muttering, hitting his head and talking nonsense. Just recently he keeps saying he wonders how it feel if he sliced his wrist.

My question is if we force him to get treatment - involve the police  to take him to physiatrist hospital. Will they accept him? So far the hospital keeps insisting we must get reference from MO which we already told them it's impossible as he refuses to leave the house or go anywhere.
