This always tends to surprise people, which is encouraging - most mom's probably do not bully their children - but it might also be an unrecognized issue.

I would describe it differently, so I don't think I had it as bad as you, but I would say that my parents did not adequately prepare me for responding to bullying, and I likely did the exact wrong things as a response. I cried. I showed weakness. And the bullying continued for a long time - most of my elementary and secondary schooling.

I would say that I eventually formed a self image that went outside how my peers treated me, but then again, decades later, peer interactions can trigger strong emotional reactions.
