from what i see youre a girl
and well us girls we like to eat chocolates when we're upset
and when you cry well your obviously upset
so your body is yelling to you EAT CHOCOLATES
and it comes out as hunger and you forget that it was the chocolates you were supposed to eat
I'm not exactly sure.... but it could because food can be a comfort. When you are crying you want something to comfort you typically.... and if you are like me and love junk food..... then you find whatever it is that makes you feel good.
I would say stress. Your body when you cry is looking for a relife which is food? i rly dont know haha
