I've been sorry to hear this too Fifty. I also have two good friends with MS. The one who was diagnosed 18 years ago was a great musician. She played one last recital with me and hasn't played since. But she did have and still does have a great attitude. She's learned what she can do and how to take care of herself and has a great husband who helps. It sounds like your DIL has that plus a great MIL. My friend certainly does things differently than she would have otherwise, but she also leads a full, lovely life. The other friend is in her late 60's and goes to the gym every day. Unless she told you, you wouldn't know she has it.
My wish for your DIL (and for you) is that she will get the right medication to stabilize her condition right away and that she has as good an outcome as my friends have had.
