Yes i have been feeling the same. I am actually getting married in 4 and a half weeks, i have been so close to calling the whole thing off because of my emotions. i feel like everyone is ganging up on me and i have had the feeling i am making the wrong decision lol. i have only felt this way since the pregnancy. But i have also been getting angry at the drop of a hat and snapping at people, over reacting and then just bawling at the drop of a hat. :-( its amazing how these hormones mess with your mind. And it doesn't help that the m/s, headaches and tiredness get to you as well.
Ok well enough of my venting lol.
