If I screwed up with her this bad, how will I ever make it through the teen years?

If I knew I'd get pregnant and become such a screw up of a mom, maybe I would have still practiced birth control after the doctors told me I couldn't get pregnant. Maybe I wouldn't have prayed so hard for a child of my own, just one.  All I wanted was to experience pregnancy (which I didn't even really get that) and the joy of my own child.  No signs, no symptoms, not even a belly. Had I of known my easy pregnancy would mean I'd be a screw up of a mother, I'm not sure if I'd do it again. Yeah, okay, I would do it again, but that's only cause now that she's in my life I can't dream of my life without her. I can't remember my life before her. 

I love my daughter more than life itself and I'd glady die for her if it was necessary, but everyone just has an opinion on what I've done wrong. I need hear that I'm a good mother and I'm raising her just fine. The only people that ever tell me that are people that aren't in our lives (except for playdates every so often). 

So please world, if you have anything nice to say, I'd like to hear that, cause I'm really starting to question myself on being a mother. I'm starting to think that maybe God made a mistake when he let me have my girl.
