Has your husband been checked over by his GP? Thyroid check and the what not? I would suggest that, if you can. I would also research the role anger plays in depression and other mental illnesses.

I'm not saying that he is mentally ill, but there seems to be a link between them.

Just throwing it out there from personal experience.
