Chronic illness and relationships

I was diagnosed with a serious chronic illness this past year. I feel unwell almost every day and it's taking it's toll especially being a mom I feel like I never get a break to rest and feel better. My husband is pretty much fed up and told me he is tired of hearing me complain about my disease every day. I understand but I am going through such a hard time accepting it and experiencing pain every day and the gloomy outlook of the disease and everything. I try not to talk about it with him but he can see when I'm not feeling well and my symptoms are hard to hide and I've had some emergencies. He is so angry and seems so resentful about it It makes me feel horrible and idk what to do at all. Especially because I can't help it. It's making our relationship miserable he seems mad at me all the time and snaps at me and if I mention anything about my illness treatment or symptoms he flips out and says he doesn't want to hear it. Anyone been in this situation?
