I'm home! What a relief.

Hospital was definitely the right choice. I was very suicidal and so I was immediately put on one-to-one (as in, supervision by a mental health worker at all times). This made me feel safe and taken seriously. One-to-one lasted 4 days-ish and then I hung around on the ward like a normal patient for a while.

Here are the stats... suicidal thoughts nearly gone... psychosis about the entity nearly gone... depression mild. Diagnoses schizoaffective and OCD.

Thanks to everyone for the support leading up to this. Your advice was invaluable.
