I think my husband is ADHD! I need help!

I have been married to the same man for 10 years, together 12. We have known he had undiagnosed ADHD a child and the last 2 years his symptoms have increased, but, even though I am an RN, I had no idea that they were symptoms of ADHD until today. I read an article and ALL his "issues" can be grouped under that "label" so to speak. Insomnia. Irritibility, Mood Swings, lack of trust, depression, anxiety (which I believe causes his stomach upset, feeling as if he has to have diarrhea, but nothing happens). I want him to go get help. He knows he needs it. He blames his feelings on me because he is a stay at home dad, by necessity, not by choice, and I work midnights. We have 2 boys, ages 6 and 4. He has about 15 projects he has started and not finished and thinks if I could be on a dayshift that this would alleviate his issues and he'd be able to "get things done". He does a great job taking care of the kids and tries to do the chores, but he is almost resentful and thinks I should be contributing to the housework more. I think that if he didn't let the stuff pile up in the first place, we wouldn't have an issue. He says he'll work on it, so do I and then it just goes back to the same. He constantly complains. MOOD is Usually worse in the morning. I tried to show him that treatment would help eliminate a lot of what ails him and he won't go unless insurance will pay for it. Currently have no insurance. I am at a loss and don't know what to do. I work at a busy GM assembly plant health services dept. I am an RN but if I go anywhere else, no dayshift jobs are available usually. I like working nights but have recently been diagnosed with clinical depression and placed on Zoloft. I think I have Work Shift Disorder and lack of Vitamin D (never see the sun), which Depression can be a symptom of. I also have anxiety and take Klonopin. This all started after children and I started having hormonal changes. I want to feel normal and when he expects all these things from me it makes me not want to do anything at all! I am working on me. I am researching other ways to increase Seratonin levels but it takes time and i only have been recently diagnosed (2 weeks). The difference is I am actively doing things to help me, and he is thinking once I am back to where i need to be, that he will be fine. I disagree. Anyway, if anyone can point me in the right direction or comment, share a story, Anything! I feel alone and desperate to keep our family intact.
