Depression while pregnant

Alexis • Texas girl. I love my soldier . Due December 30th !
So I'm going on five months , and I've been married for two. My marriage is really rocky right now, we just moved across the U.S I have no family where I'm at, my husband doesn't want to be around me and shows no affection towards me and I don't have any friends here to even talk to. I'm very depressed and pretty scared all this stress and how I'm feeling will cause a miscarriage or some type of other defect. I'm just in need of any advice because I'm pretty sure the way this is all going I'm not gonna be okay by the time I'm due. Any marital advice or any in general
