wtf crying

I just got back upstairs from walking my friend out of my building after visiting me for Halloween. I start talking to my roomate and then I decide to go to my room and chill. Then I just start crying. No reason. Sure I was looking at instagram but isj what triggered my tears. Wtf eyeballs?? I just start uncontrollably crying and I get a call from my mom. Big mistake. I answer and starts talking and then start crying even more. Then I stop for a bit so I hang up because she got busy. So I go to take a bath and maybe cry some more, but I pee first. Literally just started my period.....wtf
