You can't see my strength

I've lost track of the number of times in my life that I've wanted to give up.The number of days, of moments, when I felt I could not longer tolerate the pain or keep up the pace of my life.But I'm still here. Don't ever tell me I'm weak or lazy. Just like you can't see my illness, you can't see my strength.
I'm living with Fibromyalgia.
