I think I'm losing it

I'm 10 weeks and I feel like I am just going crazy. Not only are my emotions all over the place, (all I can seem to do is cry or be cranky) but I can't even find food that sounds good. Even sitting here thinking about going out and getting something and still nothing sounds good. I feel so depressed and lost. I really hate myself like 24/7. And I just want to hurt myself. Why am I not normal. Why can't I deal with being pregnant like most women can. At my 8 week appointment I told my OB that I hadn't been feeling good. That my emotions were all over the place and hard to control. And she didn't even really respond to it. I just idk. I feel like I'm just failing...
