Brought this up and got MANY responses on Facebook so posting here as well:

a woman in my building said "wow - you're tired now? You're so young! If you're tired now you'll be dead by the time your 60!" Wasn't wrong to want to smack her, imo. I just said 'I have MS and "total fatigue disability'" but she still went on and on about how "young & healthy" I looked (what an IDIOT!) Grrrrrrrrrrrrrrrr
