Acceptance and Raging Jealousy with Fibromyalgia and Chronic Illness

Just because I've long accepted my chronic illnesses doesn't mean I don't periodically wish for more. 

I've accepted who I am and feel well adjusted to my reality.  My limitations.  The fact that I can, in theory, do whatever I want but may be in great pain while doing it, pay for it greatly later, or completely peter out while in the middle of it.  I am still a loving, kind person who volunteers, helps friends, who is optimistic in light of many personal roadblocks.

But I'd be lying if I didn't voice the other side of it.  The feelings of raging jealousy at those who can do the things I'd love to do.
