People who have not "walked a mile in your shoes" (forgive the idiom) just cannot understand. They cannot feel the pain, do not understand, and cannot possibly help you feel any better--even though, some sweet folks may try to show compassion.
People who are close to you can see it in your face, can't they? When you are having a bad flare? Those with whom I work despite the fact that they've only known me a short time, have no idea how full of energy, passionate, and filled-with-life I was before this illness.
On not giving a rip how they react: I tend to feel that way, too, from time to time! I do not think I'm weak but in their eyes, I tend to see that--especially administrators or bosses who want to recruit only preppy, upbeat employees or teachers.
To heck with them; however, putting on a happy pappy face is necessary when you work in certain situations. (teaching!) Yes, trying to find the good in a situation may help, but when you feel lousy, your side hurts, your bottom feels like it has been set on fire, and you cannot make it to the bathroom quickly enough, you just cannot pretend to pull yourself up--not even by your bootstraps. What is sad is when the bad days overtake the good days!
I, too, am so happy to hear that people on here have found ways to make it better. Learning from those who've gone before sure helps! I love your tips, ideas, and hearing what works. One size doesn't fit all, BUT it does help to have some fresh ideas to try.
