Very bad times

DH cannot work any more - his health is too bad.  He also appears to be in the beginning stages of some sort of mental decline, which worries me greatly, but his doctor does not know the cause.  My fear is he is in the early stages of Alzheimer's.   I found out that he's been hiding debt from me.  We've struggled greatly with the expenses of another child all the time we've been raising our grandson - had to refinance our home and cash out all of the equity and I emptied my pension fund to pay his five-day hospital stay when he was born because he was not covered under our health insurance.  Plus the expenses of daycare, etc.  Now DH just admitted to me that he has huge credit card debt that I knew nothing about and we have no way to pay it, so he went to an attorney to file bankruptcy. I feel like a horrible deadbeat.  I have NEVER not paid my bills - EVER - never even paid a bill late.  But there is no other way - we can't pay the bills if he can't work.  This is going to be the hardest thing I've ever done in my entire life.
