Re: Losing everything...
I'm sorry you're in a very bad situation right now. This is only my opinion, but I'd tell the therapist everything... as soon as possible. I take it you're going to a psychiatrist as well for the medication perscriptions? I learned the hard, hard way that if I didn't tell my therapist everything, she was only able to help me on the surface... and my problems kept coming up again and again and again.
I don't think they can force you into a hospital or treatment. However, you can be labeled as "non-compliant" like me and the psychiatrist may drop you.
Is there a possibility of going to stay with someone, like a mini-vacation for you, until you can get your racing thoughts together? Or agree with your husband and kid(s) that you will not interact in any way, shape or form with the kid(s) for awhile, allowing your husband to handle all the details? If not, I think your husband would have to go the legal route to get you removed from the premises. Believe it or not, I've got a girlfriend going through this EXACT same thing. I hope I've helped some. Plese take care of yourself.
