Few days ago, i've this problems when i feel hungry im very aggressive and needed food urgently i don't know what's happening.

Sugar level?: You do not mention how long in between meals, but sometimes when your blood sugar drops it can make you very cranky. I would suggest you get a good physical exam.

Hypoglycemia: Hypoglycemia among other disbalances, can cause episodes that resemble your description. Get a check up. See your dr or a psychiatrist to clarify this. Best of luck.
