mood swings/pms

I am 9 dpo. Af is due on the 27th. Other symptoms I can handle but I have been so moody and irritable lately. Everything is driving me crazy! And it's minor crap that doesn't matter at all! Yesterday I sat in a parking lot bawling my eyes out for no reason at all. Just cause I was overwhelmed and today I'm so irritated I could scream. Sorry really just needed someone to tell me I'm not insane
