My bringing was awful, and I do wonder how it effects me now. I feel disconnected from my childhood self, so it's like the memories belong to someone else.
There's also still some carry over with behavior, which I know is irrational, but I can't shake it. Such as not being able to leave food / drink unattended when out of the house - this has it's roots in my Dad repeatedly telling me he'd poison me one day.
My Dad was a raving alcoholic, and I was the person he'd take it out on. I saw multiple suicide attempts from him, he would beat and throw my Mother (who also tried to kill herself a few times.)
During my school years he'd keep me up until the AM, screaming, kicking the sofa in front of the door, trapping me down stairs with him.
I used to sleep with a knife under my pillow, convinced I'd have to kill him one day. Memorable events include one night where he snapped and tried to kill me, I had to escape out of a second story window (I was 14) and I managed to safely get to a neighbors house, and they drove me to relatives.
This all sounds terrible, and barely touches the surface, but I'm either numb. or have let it go.
He gave up drinking when I was 17, and he's a different person. If I ever brought this stuff up, my Mom would cry and accuse me of bringing up the past. We actually have an "OK" relationship now, and I don't feel damaged as such, but it all has had to have some effect.
I've never spoken to anyone about this, and tbh, I've barely talked to my wife about it. I think it would be interesting to speak to a professional, to see what would happen.
