Sounds like you speak from experience!
Well, sure I do, but it was like that for a lot of my friends growing up, I had friends who had it even worse. I don't think my situation was unique by any standards. It's a controversial topic, but some people can grow up and not be too affected by poor parenting while others are deeply affected for a lifetime. Due to the unique nature of child abuse and it's universal acceptance on some levels, a lot of adults remain unaware of their own childhood torment.
One of the features of child abuse is that for a child to psychologically survive they employ certain techniques to repress, minimise, deny or justify the abuse. It isn't uncommon for adults to claim they had a wonderful childhood and yet they suffered horrible abuses. This can happen for many reasons, but often they may be vaguely aware of some unconscious discomfort regarding the issue, and they fear that if they explore it their will also be a reservoir of pain and discomfort underneath it. The problem is, if it isn't dealt with, may people repeat the same patterns in their life, so for instance, if they come from an alcoholic parent, they are likely to attract a similar scenario in their adulthood. It's a complex issue, and not one easily explained in a couple of paragraphs.
