Bottomless Pitt

I have a problem, a huge problem. I AM A BOTTOMLESS PITT. I am always hungry. I get up eat breakfast, then i go for seconds and thirds. Its not just breakfast. I eat all day long, I dont know why or what causes it. I do know that i was not always like this. I, at first did not notice this, until this past summer, i found myself always going to the grocery store, i would shop for hours when my craving hit me. I would pick up one thing then another, and another. Then i would catch myself and put the items I THOUGHT I DIDNT NEED back. But i would buy them anyway. Some days i would sit down eat a meal and be full, no lie 10 maybe 15min later i would have a desire for more food. Im full there is no more room inside of me and i would stuff my face anyway. Not normal i know, I am a person who until after my senior year in high school weighted less than 100pds. Until a year ago i weighted 125pds now i weight... and i dare not say it out loud so i will whisper it.... I weight 168pds. Talk about a wake up call, i have since then tried to curb my habit to no avail, i skip meals(very hard for me my stomach growls,hurt, and my heart rate burst), I tried eating friuts,yogurt,and nuts in between meals. I work out 3 days a week for 2hrs a day. Thats a waste of time since a soon as im done food calls my name. Nothing works. NOTHING! Im really afraid there is something more going on inside of me something wrong. No it not a baby. I watch those medical show where the show th over weight person  stuck at home, bed riden and i know i do not want that to be me. The sad part is i sometime forget that iam no longer a small bodied person and when i see a big person i say.... how could they let themselve get like that. GROSS! News flash, i should know.
