You may have more than depression going on for you.

Psychiatric medications can help; you need therapy, in my view.

If you can gently tell your husband that you may be risking hospitalization unless you
get psychiatric help, maybe he can understand that what you're experiencing isn't
anything like schizophrenia at all and that medications can help you.

Frankly, his fears are largely unwarranted and you need to get help whether he is
willing to accept that or not. Having your situation improved may help him to learn
that psychotherapy can be a very big help in freeing you from a bondage like depression
(and maybe another illness in there, too).

Take care; get the help you need first, then help your husband get help.

Take care.
