What do u do?

For the past 3 months i have been soooo emotional and the smell of food makes me want to throw up it is like the smell of the food makes me sick to my stomach but i get to the point when i get really hungry and can never get full...my period is different my boobs feel way move sensitive , I sleep a lot more and I am in a lot less pain and I get a lot of tissue on my pads..does this happen to anyone else?
