I'm really sorry to hear your feeling like this. 15 is hard enough, without adding the hormones of your first trimester. They can make you feel really crazy at times. When I was pregnant, my first trimester and even a few weeks into my second trimester, I'd get so hot-blooded at just this one person, I felt like a total b!tch all the time in general. I hope when your 2nd trimester rolls around you start feeling less like your boyfriend isn't a "jerk." In a few short weeks, you'll feel much better
