i am constanly dizzy and a little nauseous. when i dont eat i get sick feeling and a little shaky sometimes, irritable, dizzy and weak. then when i eat i dont feel any better. and im hungry an hour later. it feels like im always hungry! but im not gaining or losing any weight. im just sick and hungry all the time. whats wrong with me!!! can someone give me their thoughts!? p.s i cant be pregnant because i havent had sex in a month and a half and i was on birth control. plus my period came and went.
