Being on line I hope that you did a search for other web sites to get info on how the disease can affect people. You don't necessarily have all the symptoms, but the common one and hard for loved ones to understand is fatigue. It is even hard for me to understand the once totally active person I was to rarely leaving the house because I am too tired...I also have two kids under the age of 4 and am a stay at home mom...I am sure that is a contibuting fatigue factor. It is a frustratring disease because you don;t know if anything will happen or when it will happen very unpredictable. You can have great days and you can have monsterous days.
In short find out all that you can through ms societies on the web read about it, go to the library and check out some books. Above all keep being her friend just like always, and ask her how she is doing. Pride will always kick in for her but eventually you'll wear her down and be closer then ever!
