I am sorry your husband does not respond in a manner which you find helpful.
One of the diagnoses I deal with is BP-2. When I am at my worst, having difficulty functioning, and I am feeling suicidal, my husband will stand by me.
He makes sure he is around more, etc. We talk a lot. Yet, he will also share that he often feels lost about just what to do, how to help.
Does your husband feel lost about how to respond, too?
Have you asked him how he's doing and how he feels when you are suffering?
Heart-to-heart conversations can help us to understand more about what's truly going on for each person involved.
I hope you and your hubby can have a heart-to-heart talk.
