Laura,
Welcome to the forum! We all feel the same way you do. When I was new to the forum, one of the other members showed me this site: http://www.butyoudontlooksick.com/the_spoon_theory/
Granted, it's written by a Lupus patient, but it rings true for us as well. My sister has fibro, and she uses it as well. It's hard for people to not understand that we just can't take a pill and feel better, or that we're not just lazy. My husband and I know the bathroom
locations of every store that we visit just in case I need it! We've kind of made a game of it...a "find the bathroom" game!
And I'm lucky enough to have a mother-in-law that has stuck up for me when other members of his family ask why I'm in the bathroom all the time or why "I'm being so lazy". They just don't understand that we only have so many "spoons" to spend a day!
If you lose friends, then they truly weren't your friends in the first place. My friends have come to their own understanding of CD, and they know that I'm not just "blowing them off" when I call at the last minute, very saddened that I can't go out with them. I try so hard sometimes, but my body just won't let me!
*hugs* Hang in there, and know you always have friends here that won't judge you, and that understand exactly what you're going through.
