I feel like a horrible mother

My daughter is 8 months and I feel like I’m not connecting with her. I’ve worked with children my whole life and it feels like that. Like she’s mine but not really mine. I feel like the worst mother on earth. Why don’t I feel anything. I want to love her so bad I’m scared I made a mistake. I’m so scared. What if she hates me ? What if I never feel anything. What is wrong with me ?
