I think witnessing your mom's distress at that age would definitely have that kind of effect on one's psyche. That was rather irresponsible of them I would say.
Considering you practically had to raise a kid while you were a kid yourself, I can understand why you weren't maternally inclined. It's not the job of a kid and should never have been your responsibility.
My parents were a hapless pair, but they didn't plan parenthood. We were accidents, as they never tired of telling us. On the positive side, it helped to mould me into the responsible, well-rounded individual I am today:)
