First time mom, Pregnant & Single?

I'm 24 today, and 15 weeks pregnant. I've known the baby's father for 5 years and since becoming pregnant all of his lies are coming into the light. He had not attended a single apt, hasn't helped with anything at all, and treats me like a child. So far I have almost everything big the baby will need and I am working on the small things now. I have family support but still can't shake this feeling of depression and disappointment I have. I feel so bad for my baby that the father is already not involved. Single and pregnant sucks.... anyone else going through this?
