Is it normal for me to be wanting every food i see!!?

So today i went to the store and every image i would see i would crave that food! And yes i ate before i drank two large milkshakes large fries and an Italian beef. And i was still craving for more food. Plus afterwards i drank a dr pepper and i craved my brother Gatorade so i drank that too and still felt hungry! Even before i threw up because woke up nauseous this morning. This isn't normal no more! I'm getting worried.

I am sexually active and we don't aways protect ourselves.
