I don't talk about fibromyalgia much except on this forum. I don't want to because I don't want to constantly be thinking about it. That just makes things worse for me. I have a life to live and to enjoy, just like everyone else. I just happen to have fibromyalgia.
Your family knows you have fibro. Don't act like you are sick if you are feeling fine. If they mention about the fog being bad sometimes and not bad others, let them know it is a cognitive memory problem and it usually reacts to how much pain you are in. Then drop it, Sue. You've explained it to them. Ignore any other comments or change the subject or walk away. Only YOU know how you really feel and you really don't owe anyone an explanation. So, don't feel badly or let this eat at you. You can't change them and the understanding problem is with them.
