Wow, what a horrible experience! Maybe your husband doesn't know what to do when you have hallucinations. (I don't know your situation very well.) Have you told him what you need and he's simply not doing it? If so, he's heartless! I admit that I don't know anything about hallucinations or how well they respond to medication... Perhaps you do need more or different medication since the hallucinations are so strong... I'm sure that more meds is the last thing you want because of the side effects.
I know what you mean by therapists not caring much if you're not actively suicidal. I've had pdocs like that. So long as I'm not in the hospital, they've done their job and I should just shut up and go away. Grrr! I fired those doctors.
I hope things are better tonight.
