Why do we become so emotional during that time?

Dee • Just here looking for friends to chat with. Seems like you can always open up to complete strangers rather than your own close group of friends.. I'm 30, I'm single, no children && I'm looking for love. I know cheesy but I'm a hopeless romantic
I hate the fact that I get super emotional during my cycle. I begin to over analyze EVERYTHING!!!! Like the guy I'm talking to....I start to question; does he really like me, is he talking to other women, am I even his type.??? This shit becomes frustrating. But once it's all over...he's my big teddy bear!!! Am i crazy or what?!?!? 
Even me ranting like this shows; IM ON MY CYCLE!!! 🙄🔫
