I find it a source of endless surprise that people old enough to know better see nothing wrong in judging children on completely inappropriate criteria and interpreting children doing child-like things, to fit arbitrary stories and roles.
I was the awful one in the family, horrible, nasty, thoughtless, cruel, selfish, demanding, 'not right in the head', deliberately making everyone's lives harder and upsetting etc etc etc.
I believed it through my teens, and actually my 20s too, as I struggled to deal with the fall-out of a very damaging childhood.
It's only since having my DS that I've been able to revisit and re-evaluate events and see how very unhealthy and abusive my life had been. It's when I glance at my little boy, and imagine the things that happened /were said to me... And notice my instinctual reaction to protect him from hurt, and I look at him, and see a little child, and feel how out of kilter my mothers reactions were towards a dependent, loving little child.
I wish I could have worked that out earlier, but better late than never!
The event that best sums up the realisation that I wasn't this disgustingly hideous child, and that this narrative came from the adults in my life, happened when DS was only 11months old...
DS was poorly, horrible chest infection. Had just started antibiotics that day, and the gp had said to he alert that night and take him to A&E if he got any worse during the night. So, he was in pain and utterly miserable, breathing eased by holding DS upright & los of comforting the poor little chap.... My mother insists on taking him, then two minutes later I hear upset and rush back in time to hear my mother exclaim 'oh he HATES me, look at him, he's REJECTING me, he wants to get away from me, he's HITTING me - look!'
Poor DS was crying and whimpering obviously feeling miserable and poorly, and he was arching his back whilst wailing/ trying to breathe, so pushing up and backwards with his hands on my mothers chest.
Far from arousing pity and concern, she felt nothing except hurt and anger.
I was staggered. How could she misinterpret a baby's actions as all about my mother and DS being 'nasty' to her? And that was her gut reaction to a baby in pain was ignoring needs, projecting adult emotions and actions onto an under 1 yr old, and then pushing her emotions and hurt onto a baby. Ugh!
I'm glad I don't live in her head, where it's more believable than 'he's poorly and in pain'... even though she knew he was poorly and in pain. Ultimate self centred ness. Ffs.
She shoved him back at me in disgust (not gently, showing anger at him), and then proceeded to whine for ages about how hurt she was that the err, 11mth old baby had been so horrible to poor little defenceless grandma. 
Vom.
Something went click in my brain as I could see how her crazy self centred interpretations and how she acting out in 'response' ended up in such a twisted family environment, if starting from birth she reacted like that, by the time I was a toddler it would have been game over for any mother- child bond. I often felt her hatred and contempt for me, blamed myself, and was blamed by the rest of the family.., but now I see with adult eyes and know that the 'reality' I lived with was the warped delusion of adults around me.
It helped so much seeing for myself how it all went so wrong really helped me stop blaming myself, after all, my first instinct was to rush in and protect my baby from a bad situation, but when I was a baby, my mother WAS the source of the damage, and so I didn't have anyone to protect me.
Sorry a bit long, but hoping you might take something out of it too... Just understanding that you were a child reacting to damaging relationships. Maybe you were a bit tricky sometimes, but A. You were a CHILD, learning and growing, immature by design (as it were), not as a flaw!, and B. You might have shown the consequences of a bad family environment in their behaviour occasionally, but that's not 'acting out' or 'being nasty', that would be the natural consequences / reaction to a harmful situation.
I bet you were a lovely child :)
