This is for Christina, from an article on chronic pain on PC:

Strength is a constant battle. It is a battle to stay strong when I feel like I get one bomb after another dropped on me. It is a battle to stay physically strong.

As you know, I have a chronic pain condition as well --I identified with this and thought you may too --you are very strong!!
