Second day of period today.. I feel crazy.

I always get pms two weeks before my period and I get it all.. Cramps, irritability, etc.. And now I'm on my second day of my period and I literally can't stop crying like anything someone says to me isn't the right thing and I just feel so incredibly sad. It's 11 am and I haven't even gotten out of bed but I've managed to cry on three separate occasions. Can someone please help me snap out of this, I hate it :(((((((((
