Jane,
Thank you so much for that comment! It is very comforting to know that I am not alone in my experiences and I am not just crazy with my food hoarding.
In the place where they used to starve us every week we had to see a therapist. The therapist would give us one piece of candy which we would hoard under our mattresses for several weeks. Then, when we were particularly hungry or just couldn't stand it anymore, my roommate and I would have a candy celebration!
That is actually a happy memory for me. That is, until they found out.
No more candy stashes.
