Emotions

I have never been a very emotional person I grew up that way. I wasn't emotional during my pregnancy. But since having my son I'm so sensitive my emotions are out of control. I can go from fuming mad to crying in a matter of minutes.(I've never had any type of episodes with my son) but my poor husband and as much as I try I cannot control it. What is going on?! Please tell me I'm not crazy and someone can relate. I also have absolutely no sex drive. At all!! Nothing lol. No interest I could become a nun. Should I go talk to a doctor could I have a hormone imbalance? I did take clomid to get pregnant I don't know if that matters at all. Any thoughts?
