I've never felt any real connection to either of my parents. My father died from suicide when I was still quite young, so I barely knew him and my mother feels more like an acquaintance to me than anything else.
There was a time where I hated my mother for the way she treated me while growing up and staying in abusive relationships as long as she did. I despised her being so weak. After awhile though, I stopped hating her, but I don't think I ever loved her either and I'm pretty sure she knows that.
