That's my biggest fear. My brother was diagnosed with MS 12 years ago, and so far has been without problem. But I worry that it will change one day. There's just so much uncertainty with that disease, it's hard not knowing a certain timeline for progression. I know it's hard, but the best thing you can do is be strong for her. My brother and I are riding our first century Sunday for the MS Society, I'll be sure to keep your mom in mind. Maybe she'll get me through those last few miles.
