I just say to people, or have my DH say to people. "I have good days, and bad days." If I feel okay that day I say it. They ask, "How are you?" I say, "Today I feel good", or whatever.
If my DH says something stupid to me, like trying to compare me or my energy level to his, or not being able to go some place he wants to go. I just tell him, well I have MS. You should be thankful you don't. Or I joke back and say,"Want to trade places?".
He gets it, when he forgets it, and so do others, but nicely.
Do I feel guilty, absolutely. I feel some days I am holding DH and family back. But I turn on my brain and say, "If you want to go the store, then go-if you want to visit someone then go visit."
But I would
never take any cruel words or gestures from anyone. Not even my family. After all, it could be them, and not me. I would never make fun, or jest at another person's illness.
I didn't ask to get MS, it is not my fault. That is my only mantra to myself. It just happened.
We can, on bad days, turn whatever someone says into a negative sentence. We just have to learn the difference. They might mean something else, ...or maybe not.
