Shagmund, thank you for your honesty.
You are likely to have it ignored by many on this thread, who will continue to just repeat, over and over, that they would/could never reach that point, no matter what happened, no matter what the context implicitly suggesting that they are stronger/more able/better parents than you for not experiencing your pain.
Garlic, there is NOTHING I am "betraying" about myself. I am very clear about this. I didn't have a "happy" childhood, but it is not because my mother smacked me.
My father, severely physically abused himself, made a plea never to smack. It was his "last resort". However, he was a rage-filled, desperate, hurting man and while he never raised a hand to us, he spent most of his time either a) falling down drunk (avoiding his feelings) or b) roaring, shouting and being nasty with his words.
My mother, like Shagmund above, was in a desperate situation and sometimes she lost control. Do I think that was great? No. Would I wish to repeat that behaviour? No. Do I think THAT means it is valid/helpful to then say that she "damaged" me (implying, as these sorts of words do, that I have no choice in how I act now?) and that I "hate" her, like a toddler/teenager says they hate their parents.
It is not "weak and immature" to notice that your background can have an influence on you, I agree. I would maintain it is immature to maintain a rigid approach to your parents' suffering and use childish words like "I hate them", "I was smacked once and it was shocking and it has always damaged our relationship" or "I still feel bitter and distant from my mother because once she smacked me".
This is what happens on threads like these. People who remember a painful one-off or irregular event write about it affecting their present functioning as adults when they have full control over how they act. Being smacked/hit/hurt does not mean anything, sorry folks, and it is buying into the idea that it defines you that causes much adult psychopathology.
I emerged from my childhood aware that it was both good and bad, with lovely moments and with terrifying moments. I did well at university and in work. I met a lovely (non-abusive, non-addicted, loving and responsive) man. Life was really fine. Then I had a traumatic birth and in the Western way of things, I started searching searching searching for "why" it had upset me so much. The professionals I dealt with pretty much told me that it was a "normal" birth and nothing to fear (I had a Kielland's forceps birth, with a baby with a low Apgar and I couldn't walk for months after it) and time and time again nodded sympathetically but said my fear was irrational. I started to research it online. Why was I so terrified? Oh it must be that all that stuff I had always been told was true. I WAS defined by my childhood. I hadn't managed to emerge as functional as I thought.
It was THIS that began the suffering that led to a diagnosis. Not the suffering of the past, but my relationship to it in the present, a present in which suffering/fear is something that "betrays" you, that "means something", in which your past defines you.
There is a developing psychological literature on this you know, risk vs resilience and acceptance vs blaming the past for your current relationships.
Maternal mental health is always the dinosaur in the room on threads like these. Yet people quite easily talk about smacking as though it were equivalent to severe abuse and capable of provoking long-standing mental health issues. I really don't believe ANY one off smack in childhood has that capacity, I think it goes against everything that is known about behaviour and how we develop. I do believe that hurt breeds hurt and that the person who prosletyses about how they would never do x because they are above it will have their own peculiar ways of exerting control which may be just as damaging and even more so than smacking.
I have no issue with discussing this because I don't think it betrays me to describe my childhood. It doesn't define me. It doesn't mean, well, anything. Very few people who have not had therapy believe that to be true within our verbal community. We are still reeling from the effects of the Oprah generation where any pain in childhood is a get-out-of-jail-free card for your feelings/behaviour now. I don't buy it.
