Why do I get FITS OF RAGE when I am extremely hungry?

This rarely happens but when it does its bad. I seldom allow myself to get really hungry, but I can remember two times in the past 6 months where I was very hungry and it resulted in me being EXTREMELY angry and in a really horrible mood. Both times I hadn’t eaten all day but I did drink coffee. Yesterday was one of them, reason why I hadn’t eaten being that I felt like shit all morning but once I felt better I was really hungry but I was in a movie (Daybreakers, please save yourself and don’t go see it!!!) so I couldn’t eat then I was busy, so yada yada yada I was starving and then the awful mood kicked in. This time I was with my boyfriend and I did not want to be touched or talked to and every single thing he said and did annoyed me and I never get annoyed with him which is why this is so odd. And while I’m in these moods, I know how horrible I’m being, but I still can’t snap out of it.

So this really isn’t a major problem because hopefully I won’t allow it to happen again lol but is there a connection between like…some happiness hormone and food/hunger that I should know about? If it matters, I usually have a gigantic appetite and I am always eating. I’m always happy too…so I’m lead to believe that these 2 go hand in hand, lol.
