Hi and welcome,
A lot of MS symptoms are invisible to others, one of the most common comments pwMS hear when they mention MS to people is "but you look so good" and if your having a bad day it really can be frustrating....each pwMS has a unique combination of issues, fatigue is a big problem that limits what most MSers can do on top of everything else your dealing with.
Knowing your not alone helps, venting with other MSers when your having a bad day helps, laughing with other MSers about the weird and bizarre that has become your normal helps, talking to a counsellor helps...
I hope that helps answer your question.....JJ
