SW: I think the biggest advice I could give a fellow MSer is that if you walk one block today, walk two the next time. Each time you get out make the effort to make a small improvement on the last time.
Don’t be discouraged. It doesn’t matter how far you went, what matters is that you got out and tried. Eventually you will get stronger, and you will get more confident. That is what happened to me. I went from thinking my life was over at 30 years old to running my first half marathon before my 32nd birthday. MS or not, you can do anything you want, but you have to will yourself to do it.
