Hormones? or something else?

Ok, so lately in the past couple of months i've been getting lots of head rushes, hot flashes, extreme pain that induces puking during my period, and at night i get these urges of extreme hunger, more like "The Munchies" but nothing sounds good to me, but i feel like if i dont eat i'll puke... and then afterwards i usually go through emotional fits that are usually in this order Happy, Sad, Angry as hell, Sobbing, Happy again. And im paranoid as heck, everything seems like its out to get me, and i swear i hear people call my name, and see things all the time. so im wondering if maybe i just have some hormonal thing going on, or maybe a mental thing. oh, and im mid teens, so im not like, going through some hormonal early menopause or anything.
