I noticed your mood said you are exhausted. It is good you are exercising because it has always been hard for me to sleep when I do not get some exercise everyday.
Perhaps you need something to help you sleep. I have some physical pain and when I get overtired the pain kicks in. I alternate between 3 things, Gabapentin, Xanax and Diphenhydramine (cheap, OTC allergy medicine)--I try to only take the Xanax every 4th day because it is so addictive--I know I am playing with fire--but I also have to function, need relief. Have you spoke to your doctor about a medication to help you sleep?
I hope you get some relief soon.
