Tired of my Fibromyalgia

My fibromyalgia is getting me down today. I try to stay positive and active because I need to be there for my daughter who is very ill from her neurofibromatosis and cyclic vomiting syndrome, but somedays my own pain just seems to take over.
I feel selfish when I just want to curl up and go back to bed, but I can't.
I am grateful to have my Lord and Savior who gets me through these times and walks beside me everyday every step of the way.
