Hi garnet and welcome!
I know it's hard for people to understand what we are going through. I was one of them until I got fibro. I would hear about fibro and knew a couple gals with it but I had no clue really what it was like. I don't expect other people to understand this anymore because they can't- but I do expect people to have some compassion. And it sounds like your coworkers have none. So sad!
Wish you luck with your rheumy appointment today. Let us know what happened.
