My family life definitely had an impact on my AvPD-like thoughts and behaviours.

My dad was relatively absent and my mom ran our family like a business. There wasn't any affection shown, there were high expectations set for behaviour and achievement (add to this a level of sexist gender roles so expectations for me were much higher than for my brother), no praise (only time I've heard good things about myself has been when my mom talks to other people about me and basically is using me as a trophy of herself and how great she is...), my mom and brother are both rather explosive and aggressive, I didn't have the same sorts of interests as my peers, my family was essentially the 'black sheep' on both sides of the family for different reasons, etc etc etc.

It's just how it went.
