How does my family do it?

That's my question. Spending hours in waiting/family rooms and obviously endless-feeling days/nights in the hospital just..waiting. Driving hours back and forth for doctor appointments or where ever I am and need to be. All while managing their jobs, school, and kids. Just with a blink of an eye, they drop what they're doing and come to my rescue. I know I've taken my family for granted, but never doubted their love. It's amazing what they've all done for me or put up with, with my all of my health issues. All the while, still able to put a smile on. It takes a lot for parents to watch their child get poked with needles and hooked up to a bunch of wires. I know if I were in their shoes, I would be an emotional wreck.
