How can I stop feeling guilty about things I’m not getting done?

Fibro victims tend to be over-achievers. We have had unrealistic expectations of ourselves all of our lives. It's time to get real. Set some new goals. They don't need to be large- just realistic. Instead of cleaning the garden, weed one flower bed. You don't have to be perfect. Ignore anyone who tries to make you feel guilty. You can only do what you can do.
