I am the only daughter.
I have a brother and a step-brother, both younger.
Turns out my family had no use for female progeny. If we lived in a more barbaric society, my father would have placed me in a bag of some sort, weighted it down with rocks and thrown it into the river. To this day, I fight to maintain my self-esteem (which isn't terribly high to begin with) after speaking to him because I'm always "too fat" (at 125 pounds, really??) or "too irresponsible" (because I forgot to call him after I picked something up for him).
I know now that I will never be good enough for my parents, and that's an issue with which I struggle daily. All I want is to be able to be myself and be happy and be loved by the people that brought me into the world--it's not like I asked to be born.
