When you have to live with pain every day it is difficult to explain to people who don't. It's like an addiction that you didn't choose. Percentage point by percentage point it takes over your life, until you end up living inside the experience it creates. After that it is like a fog, surrounding you and leaving you no way out. Pain is controlling, relentless and inescapable. You try to bear it, even enjoy it sometimes by wallowing in it but eventually, it becomes the main, and then the only point of your life.
