Ruth,
Welcome to the forum.
I'm glad you've found us, although I am so sorry about all you are going through and the suffering your husband is enduring.
UC is a tough disease, and yes it sucks big time!
I think it takes awhile to wrap your head around this disease and learn how to cope.
And yes, the 5 steps of grief often take hold. So anger, depression are certainly a part of that process. Sounds like he is at the anger stage.
Would he be open to getting some counseling from a counselor who is familiar with life-changing disease (such as UC or others)? It might only take a few visits, and not have to be long term counseling, and the counselor might be able to give him some coping mechanisms as well.
At least you're coming to the forum for advice, support and for venting - which is a good outlet for you. But he certainly needs that too.
Before being diagnosed with the disease, I was a foodie and really loved food. Then I went through a period where I HATED food, because I associated all foods with UC and getting worse.
But then I started doing research, and tons of reading. And believe it or not, when you get information and lots of it, it becomes empowering (albeit sometimes overwhelming initially as well) because you see what the choices are, your options, etc... you don't have to rely on just your doctors for information.
Anyway, don't lose heart and hope; it takes time and lots of patience.
Don't feel selfish, this is a disease which affects the whole family unit.
How old are the kids? Rather than staying in denial, is there a way you could bring the whole family together (depending upon the ages of the kids) and explain what's going on in terms they will understand?
