No appetite at all, fear of throwing up!!

I'm 9 weeks today and so excited about this blessing from God. My only problem is l have no appetite at all. I have never been a big eater to start with but l thought it would change once pregnant but it's actually getting worse. I'm literally afraid to eat because the vomiting terrifies me and lm always crying when vomiting. But l want to eat because l want my baby to get all the necessary nutrients. Please help me lm loosing my mind...
