How do you feel during your period?

I'm not sure why, but everytime my period comes around my insecurities and anxiety get 10x worse than usual and I'm honestly not sure if its normal... I know people cry because they're over sensitive during their period but does it effect mental health issues? I've cried until 4AM 3 nights in a row about how I look and act other stuff and I just wanted to know if this is in any way shape or form normal...
