I'm 48, and I was diagnosed four years ago at 44. I'd had symptoms for years, but like you, stress seemed to bring about the diagnosis. Nobody causes MS by what they do. They don't know the cause of it yet, so we can't blame ourselves for doing something wrong, or lack of doing something we should have. All you can do is try to take care of yourself, and remember, it isn't a death sentence, life still goes on. It took me a few years to accept the idea of having a chronic illness, but I eventually did.
Time heals all things. The first year can be hard, because of denial or anger and other emotions. Stay in touch here, and you'll find people who know what you're going through. It might take your husband awhile to deal with it. It took mine a couple of years, and then only after we had some serious "discussions."
Stay in touch, this is a good place to share.
