Yep, this is our own personal rollar coaster ride. I just say good days and bad days, and that each of us have different experiences since the nervous system gets attacked differently.
My path has been different than my other family members. I've seen the worst case and best case scenarios with their MS. And I'm a little inbetween, LOL. So for my family, they already know that this disease is wacky.
I'm not thankful for the way they understand, but am glad they do.
On a side note, It doesn't fully explain the fatigue, but to get people to stop the "I get tired too" - I usually tell them to imagine the feeling of tiredness they get with the flu and imagine having that 24/7.
