@Kcmanby and
@Lisadee8800 welcome to the forum.
As Kcmanby says, it is important to accept where you are and not push yourself to do more or be more than you can. While it is imperativ e to keep your body moving, because inactivity will make things worse for your overall health as well as increasing fibromyalgia symptoms, overdoing exercise or doing the wrong kinds for your particular situation will do the same. So gentle experimentation into various forms of exercise is needed. Try out things you have never tried before, even if they seem too gentle to do any good, because they might be just right for you.
And, equally important, remember to give yourself credit for everything that you do for yourself. We often tend not to do enough of that, especially if we are doing less than we used to do in our lives, but it's important to encourage ourselves and tell ourselves that we are doing a good job.
Lisa, if you are not getting enough good sleep that is definitely contributing to your difficulty. I assume you have tried all of the many and various things that people recommend to do to help you sleep?
You might want to consider taking medication for sleeping. I don't mean OTC, but something prescribed by your doctor. This might not be the right thing for you, I don't know. But I was chronically sleep deprived until I started taking a medication that allows me to sleep, and I know how important it is. Just a thought...
