bad anxiety depression and suicidial while pregnant.

I've dealt with anxiety, depression and suicidal thoughts my whole life. They were getting better but now being pregnant all of it's back and worse. I still don't feel a sense of purpose and I have no one to talk to. Pills don't help and sessions don't either.  My husband is no support and will never want to understand what he's put me through and what I'm going through. He always wants to play the victim. I thought I was suppose to be happy being married and pregnant but I'm not. Has anyone else gone through this and overcome it? I know it's just going to keep getting worse I can feel it.
