I have been feeling like this too. Try having some "you" time!! Have a bath or watch a soppy movie (I have found this at least gives me an excuse to be weepy!). Most importantly talk to your partner, your mum or a friend about how you are feeling. And if you still feel this way in a week or so talk to your Dr. Hormones can make you feel insane at times so take it easy ad relax as much as you can.
