Terrified

So I’m 18 weeks pregnant and I’ve been happy with my pregnancy. I don’t think it’s really sunk in that I’m pregnant till today. This is my first and I’m honestly terrified. It just occurred to me that my whole life is changing. I’m going to be someone’s mom and that scares the hell out of me. I just feel like my life is a mess and I’m just not ready. I’m a young mom (20). I have a house and a car but I just feel like my life is over. I never liked kids and never felt a bond with them. I’m scared that it’s going to be the same with my LO. Is it normal to feel like this? My husband already has 2 kids and he’s older than I am and I haven’t mentioned the way I felt to him about this. I’m just scared shitless. Thank you 😔
