Pms or plan b? Driving me insane.

Sandra
What do you ladies do when you feel like you cannot handle anything? I feel like I'm completely out of control...A lot of it has to do with some really difficult personal things and starting school again, but I feel like I am having more severe pms than usual. 
Additionally i took plan b about 4 days ago..Have any of you experienced more crazy emotional responses to things you could usually handle after taking plan b?
