No one chooses to have this problem. It just is. Don't blame yourself. The cravings, the pain of it, these are something that happens to us, not because of us. Learning to manage it is our extra burden in life. I see alot more wisdom on this board than I do in other areas of my life, because of this extra burden. It is a very painful karma, yes, but one that strengthens our souls in the long run.
