Aww sweetie!!
It's a terrible drug. I think a card would be nice for him. I think it speaks volumes that he was also emotional watching you.
I don't think he was emotional for his situation. Just not the 'guy' thing from my experience (sorry men, no ill feelings intended!). If he was crying, he was crying with or for you, and that's a huge thing. It means he cares a heck of a lot for you.
Sounds like you have a great man in your life. Now the challenge is to stop living 'around' the disease. I worry that yes, you are missing out on life by staying cooped up to avoid a flare or a relapse. By doing so, you're putting your life on hold, and your focus on the disease.
When you're feeling a bit better, see what you CAN do, not what you CAN'T do. Put the focus there, and eventually explore those 'cant's' again, and then work on making them into 'cans'.
With that said, MS itself is an extremely emotional ride. Add to that the ugly, awful roids and you're hit with a double whammy.
Keep a cool head (as best as you can) about this one. You're not a failure by any means, and your man certainly doesn't see this either. Hold onto that one, sounds like a good man

There will be plenty of parties ahead for you.
