I read your post, please seek group support. Group support can be a blessing when times are troublesome.
Whats going on with you is not your fault, please take everthing one day at a time. Who knows what tomorrow holds for anyone, enjoy today! and your husband. Find the smallest of things that you guys can start enjoying together. If you have to speak to the doctor outside of your husband, do that. Take things slow, the ultimate goal is a harmonius environment, it's easier to come together without tension.
Support groups are fabulous, the people there have experienced what your going through if not more. They can help you work through what your feeling and positive ways to communicate it. In addition, you may find out different services you and your husband are entitled to. Never forget you are not alone, and their are plenty of people in this world full of love; willing to help.
I have Sarcodosis of the lungs, talking to people who had the desease and hearing their stories, so similair if not exactly like mine. Gave me comfort, support, and ways to adjust faster. An illness can strip you of your happiness if you allow it to. The support you need, is a support group away. Check with your doctors or the nearest hospital for a suggested support group. If you make a decision to try a support group and your husband doesn't don't worry, it's ok.
Praying for You,
