Depression

I am 18 weeks pregnant and I feel more than the usual sad, angry, ect. I feel depressed and like I'm not connecting with my husband at all. We never spend time together and I'm super busy or I never feel good. He does take care of me and such but he always says "you never feel good". Like he is mad that I am still neasous or throwing up and I'm always tired. I am in a funk and after trying for over 2+ years I should be estatic! Any suggestions? Please!
