Leaving you baby's father.

I'm now 6 months pregnant and I just broke up with my boyfriend who was the father. Ever since getting pregnant it's like he wants nothing to do with me and anytime I speak up about it he makes it seem as if it's just me being crazy. Since being pregnant I've had horrible anxiety as I never wanted to be pregnant and I feel like since he's so distant I'm really doing this alone. I truly feel like I don't want this baby which makes me feel so much worse as I feel I should just naturally love him. I'm really panicking. I never wanted to be a mom to begin with and now I'll be doing it alone. I'm just looking to see if there are any other mommies going something similar because I'm seriously feeling so alone and I keep getting panic attacks. I guess I want to see if there's a light at the end of the tunnel.
