If your psych is head of the department, he most definitely left a "chain of command" for treatment of any and all patients. You can call and get in to see that next person in line. There is no reason to wait on that.

As for your husband needing you? Huh? You need him! Everyone has to do the best that they can, not just you--him, too. For example, both parents need to make sure the kids are taken care of, not just you. I hope you will use the resources available to you there where you live. Maybe start with the psychiatrist at the hospital, but it shouldn't end there, either.
I'll be thinking of you and hoping the situation is improving for you.
