Unsure of baby

Has any felt unsure of whether or not they want their baby? I feel like I’m going to be an awful mother that I can’t be excited because I’m just going to ruin their life. I haven’t had much support just people asking questions when they want to be nosey. My boyfriend is excited but I’d like to hear from him or my mother or even one of my siblings that they know I’ll be a great mother and that they can’t wait to see how well I’ll do. I’ve even decided I don’t want to know the sex and that I don’t want to be part of a reveal. That the father can decide everything on his own because I don’t want to get excited by all of It. My pregnancy hasn’t been hard, but I feel no connection
