When to give up?

I've had terrible debilitating back pain before..................I was lucky to finally get rid of it. It can be pretty disheartening when you can't walk of even lay down or get out of bed by yourself. Vent all you want (sometimes it helps), I think most here will understand. Try and keep a cool head about you. Hope you're getting full social security or unemployment to help with bills?? My grandson works for FEDEX delivering packages, he's young but still comes home very tired and beat every day.
