I could eat a MONSTER!

I have always tri"ed" to be in a good shape and would consider myself petite as I still go to the petite-0 size section in the NYC stores.But I don't know how long this is going to last as there have been days when I have this incessant craving for food.. I just can't stop eating and this results in an unhealthy me!!
Such as today for instance, I finished a bag of chips(family size), ate 6 oatmeal bars (the one with the blueberry tart in it.. its awesome!!), 2 bars of milk chocolate, fries, nuggets, dumplings, half a watermelon ,etc etc. and now I sit here licking on a bottle of peanut butter. I know if anyone sees this list would end up thinking I am monster which I am not really~
So, at this hour of the night I sit infront of my laptop and really want to find a reason that brings out the glutton in me. Was I upset about something? Frustrated may be? Or is it the long distance from my loved ones? Or the hundreds of things I have to think about. May be it is an outbreak of a little from all these.I can't be sure what but surely eating does give me satisfaction to some extent.
But, yes I pity myself when I see myself doing an hour of physical torture in the gym. I would surely never make this a habit, else it would be me and my wardrobe which,one day would not have a single cloth of my fit!! Scary!! So, for such a price to pay.. eating is not worth but getting rid of my fears and anxieties is :)
