I'm sorry your advisors are no help. Would it be too late to change the topic--maybe to something that appeals more to you? And even to them? I picked a topic I knew my advisor was really interested in. That helped a lot.

I can understand having a depressed husband and how they can be tough to deal with. It could be a factor.

Would it help to talk to someone here about it? Lots of us have a lot of time to listen and some of us have advanced degrees.
