I can’t stop eating all of a sudden!

I feel like I can’t stope eating. Like I constantly have to have food in front of me and I’m normally not like this! 8 days until my period. But oh my goodness I just want to keep eating. And I feel like when I do eat it isn’t enough. I just NEED MORE! is this what the Cookie Monster feels like because oh my goodness. Am I crazy? Or is this something that happens?
