Sorry to hear that you are in a very difficult situation. Like all "sisiter" said, both you and your hubby are now under a lot of stress.
When situation is out of your control, I guess all you can do is try to do the best in your part(look after yourself and the family, so that when your hubby comes home from work , he has a place to relax), and wait for things to turn around.
Obviously, both of you needs support from each other. You won't be diappointed to each other if you have no expectation from each other. I see that as both of you still care about each other and need their support, so think positive.
