how does one get ride of the sense of being alone when pregnant?

Am sorrounded by people but i feel so alone.

My dad hasn´t spoken to me in 4 weeks because he shouted at me over coming 5 minutes late for dinner and i cried.

My mom doesnt advise me or talk to me about anything pregnancy yet am a first time mom.

My husband, socks in work and doesnt want to talk or know anything about the baby.

My best friend offered to listen when i need to talk, only she lives 5 hours away.

I just cant shake off this feeling of being alone yet am sorrounded by people. Am in both physical and emotional pain and no one knows. Even if i wanted to talk, there is no one listening. So i go about everything like am not pregnant despite the pain. i have become withdrawn. how do i fight off this feeling?
