i dont think i was ever grateful for my upbringing, but i always feel like im exaggerating. i coonfronted them about the phsyical abuse afew times, my mum gave up trying to deny it, then shed just say i was exaggerating, or i should be thankful i didnt have a mum like 'so and so'. and i remember the physical stuff, but its the other stuff i dont remember exactly, and my mum read my diary where id talked about it, and she didnt even deny it or ask me what had happened, she just said was i going to report my dad to the police
but yea i dont know what normal is and i think thats hard, all i know is i would never treat anyone the way they treated me.
I hope going back there wasnt too hard and that it helped you figure stuff out. they denied breaking your finger etc? or they denied abusing you? i think sometimes they dont want to accept what they did when they know it was wrong? maybe.
