maybe I made a mistake?

Posting anon because I feel like a massive pile of crap but I'm hoping my feelings are due to hormones. I'm due any day now essentially, but I'm starting to feel like maybe I made a huge mistake trying to start a family. I thought it was the right time, but now...not so much. Maybe it's because my family expects so much out of me and my not yet born child, maybe it's because of the stress my mother in law is putting on me, maybe it's just me being absolutely terrified I'm not going to be able to have the best life for my child. Does anyone else feel this way? I feel horrible, but I want to get past this feeling. I don't have any friends to turn to, I don't have anyone really close to. My husband doesn't understand... maybe I really am just a crap person for feeling like this...
