Not really sure how to talk to my wife

Me and my wife just had a baby and... Idk... I just don't feel like my daughter likes me. I'm trying to really hard but sometimes I feel like I do everything wrong. It was an unplanned pregnancy and even though I wasn't ready, I thought I could get ready, but no matter what I do it just seems like it's not enough and she will never like me. Maybe it's just all in my head. I understand babies cry... Thats what they are supposed to do but not being able to figure out whats wrong hurts me. I just feel hopeless and think my daughter and my wife would be better of without me. I've been trying to be there for my wife emotionally but it's just hard because I don't feel like myself and I've been trying to push my feelings aside so I can be there for her but I just feel even more sad... I want to tell her how I feel but I kind of suck at that. I hope I don't come off as a bad husband and father, I'm really trying I swear... Just think their lives would be better if I wasn't here...
