Hey - I know how that is.
When I was in the worst of my bulimia, when I would eat I would picture it as the vomit.
I soon realized that I was viewing my food through the eyes of "ed" (eating disorder), rather than the eyes of me viwing the food as somethign healthy and needing to my body, rather than something my body wants. It's easy to give in to the ed voice...Rather than fight it, huh? But in the end, as a girl who's been to the end and back, you become a much more stronger person if you can fight the voice. And I would strongly encourage you to find someone, an "accountablity partner" who you can call when you sense you're listening to ed, and need someone to switch you over the the me voice.
If I can help, please let me know!
Love ya,
