Kiss this MS

I made fliers to pass out to our neighbors in the hopes of getting more sponsors for the MS walk next weekend. Maddie was so excited and kept saying " this is for Nana." It broke my heart. My Mom has had some trouble with one of her legs in the past two weeks and is having a very hard time lifting it to put her shoe on:( It makes me so scared for her but at the same time motivates me to help find a cure. HOW can there not be a cure for this yet?
