Ready To Mentally Attack People

I really hate people when I'm on my period. Like every little thing irritates me, and I wanna shut down to protect everyone from my fury. Best friend is being insensitive, boyfriend is being a douchebag, and my body hates me because I'm having itches DOWN THERE. Anyone know how annoying it is?? God, will someone help me figure out how to curve these mood swings? And to stop the itching .-. that especially.
