In truth, you like the pain. You like it because you believe you deserve it.
You will not stop. The pain is necessary, especially the pain of hunger. It reassures you that you are strong, can withstand anything, that you are not a slave to your body, you don't have to give in to its whining.
[I] learned ... that friends are a good source of food and soul when one has not yet gotten the hang of cooking or living (as opposed to dying) alone. That nothing-not booze, not love, not sex, not work, not moving from state to state-will make the past disappear. Only time and patience heal things. I learned that cutting up your arms in an attempt to make the pain move from inside to outside, from soul to skin, is futile. That death is a cop-out. I tried all of these things.
At times it may seem worse - harder, at least - to live through the despair of this loss without the temporary comfort of our addictive behaviour. We cannot drown our sorrows. We must face the fact that we don’t know, really, where we are, how we got here, how long the pain will last, or how to move past it. That uncertainty may be the most painful part of not knowing a God: no one is there to reassure us that a God will take the pain and confusion away. We simply don’t know. And we have no way to numb ourselves or to forget the condition we’re in.
