Emotions during pregnancy & how people affect you so easily

I find it so strange how emotional we really can be during pregnancy. I am now 13 weeks (will be 14 on Thursday) & I am extremely emotional. It got to the point where if something wrong was said, I would cry. But i find it strange how people quickly turn on you because you are pregnant. The father of my child is even against me & saying negative things about me along with everyone else, trying to stress me out. I would constantly cry myself to sleep every single night thinking about it. I try to be positive but it would be times where I would completely break down. My father is the same way, he speaks negative of me & it hurts, but expects me to be respectful. I just can't take it. What should I do. I need answers please
