I Am 68 Years Old. Have Fibromyalgia Bad. I Am

I am 68 years old. Have fibromyalgia bad. I am anxious daily, its like a fight or flight feeling. Appetite is not good. Depressed, negative, just anxious, have to do something all the time.
At night I go to sleep but wake up with a surge feeling of anxiety way too early in the night and then cant get back to sleep.
could this be adrenal or cortisol ?
My glucose is good, my thyroid is fine.
