Please Help.. My Mother In Law Is Dying Of Cancer.

[scruffbag]

She is in a hospice and my husband vists daily.[only child, after his brother died a few years ago] She could pass away at any time.
He is still working full time, works long hours, and then goes to the hospice after work.
He is exhausted. He takes his tiredness out on me and can be very verbal.
I work part time, and keep everything else going.
We still have all four parents living. They are all in their eighties, and all have health problems.
What is the best way of handling this situation? Please advice me. I am struggling. Many thanks.
