For me it seems to depend on the level of stress or the situation. Generally speaking when I"m stressed I eat. People crave the sugar -- I read about in a Food / Mood book awhile ago - its all bio-chemical. However when I've had really catastrophic situations like a massive fall-out w/ a boyfriend, I just simply stop eating. I actually stopped eating almost literally for 3 months the last time that happened. As I sit down & analyze it, the eating stress seems to come when I feel frantic, like maybe a lot of stuff needs to be done in a short period of time (e.g. finals, deadlines, etc.) or if there's a lot of chaos around me and things can get done but its just very chaotic. But the boyfriend situation was such that I think I felt 1) a huge amount of guilt for having hurt my ex and 2) a fatalism about it - there was nothing I could do to address or fix the situation. I was completley helpless. These other stress eating situations were not characterized by a feeling of completely lack of ability to make come up w/ some sort of solution. The non-eating situation was exactly that. There was nothing I could do.
