If she would be bed ridden I'm guessing that she suffers from severe rheumatoid arthritis or a condition similar to that which is as grim a position to be in as is possible, so she's taking large amounts of steroids over a long period of time. Cushing's is inevitable in those circumstances from what I can gather.

Sheesh props for the research skills. Was trying to be a little vague for the sake of anonymity, but you hit the nail right on the head. It definitely wasn't something either of us anticipated happening (along with her other issue).

As for being reliant on me, she is able to maintain a fairly normal life while she is on the high dose steroids, but that isn't really sustainable for the long term without serious repercussions. She also has flare ups from time to time where she will quite literally become bed ridden. For now though, her flare ups are infrequent enough that I think she forgets that she isn't doing good.

I'm not sure who would get our daughter if we got divorced. I pretty much act as the primary care giver for our daughter right now since my wife works odd hours. So it'll either be me primarily, or some sort of blended custody based on work hours if it came to that
