Hello and sorry for what you're going through. Whenever someone relatively new to FM (not sure if you're new to the diagnosis, but it sounds like your life was "normal" until last year) posts about their frustrations, it makes my heart ache for them because I've been there. I also have gotten through that but I know there is no magic bullet to do so.
It sounds like you are still in the grieving process of having FM. I think it is a process to get to the point where full acceptance can help. Although I think sometimes acceptance feels a little bit like despair. But some of your angst might be caused by having so much hope at night, then waking up feeling badly, and being emotionally frustrated because of that. Perhaps lower your expectation or make doable goals for yourself. Focus on what you can do. If you can only get up, shower, and get dressed, feel triumphant for that. If you can accomplish one chore, feel good about that.
FM is often life changing. Many of us do work but perhaps in a different role or for less hours. Also, it can take awhile to figure out the right combination of therapies. For me, I do what it takes to sleep. That means melatonin, benedryl, valerian root, and others, sometimes together. Getting good sleep goes a long way to being in less pain.
Often, FM makes us have to change our perceptions about ourselves and our abilities. It can be very discouraging to compare your new FM-ridden self to your old self.
I hope you can get control of your symptoms. That helps a lot and hopefully you can move on and find some things that give back meaning to your life. Until then, don't beat yourself up!
