Hiya, how did you explain fibromyalgia to your friends and family?
I can't remember what thread it's posted in but there is a great blog on the Internet called the 12 spoon theory. I would call it a must reed. Also I have suggested I clamp a vicescripts onto my husbands biceps as tight as it would go and he spend the day like that and then imagine almost your whole body in this state day and night. He declined and has never questioned me again to do anything when I didn't feel like it he also stared picking up some of my slack cheerfully!
I've also encountered a lot of people that doubt me. Just because I'm young and seemingly healthy, they think that it's impossible for anything to be wrong with me and that I'm just making up excuses or being lazy. I have one cousin in particular who can will tease me when I say I'm not feeling well and don't want to go out and do things. It can really get to you after a while. I've gotten to the point where I'll gladly try to explain it once to someone but if they choose to continue to be ignorant and insulting, I don't continue to try to get them to understand. It just isn't work the emotional toll it ends up taking on me. People don't realize how some of the things they say hurt people, especially when it has to deal with a medical condition.I've tried just about everything possible to explain the experience to those in my life (and many more who used to be in my life but no longer are, but as @Trellum mentioned, if they don't experience it for themselves, many often will never understand. Thankfully, some are more understanding than others, and can try to put themselves in our positions. I like the amplifier example given by @DK_Engineer, I think that may help some to understand, and could be worth a try.
There's a new television commercial, I believe be Excedrin, about a girl who experiences Migraines, and they create an experiment wherein her mom is able to experience some of the symptoms (distortion of vision, etc.) that she does, and I hope someday that type of thing exists so that others are able to experience even for a short period of time what we go through on a daily basis. The fact is that many will still doubt you and I've found it best to limit my interactions with those types of people. I can't help what someone else chooses to believe about what I'm going through, but I can choose to walk away from those who make my life more difficult.
