The worst cases, though, are not the ones where there is not enough love going from parents to children. Those cases are bad, of course, but not the worst because these are children who have a chance of healing in adulthood.
The worst cases are the ones where parents clearly love, adore and cherish their kids yet fail to fulfill the most important role of a parent. And that role is letting children pass through all the stages of separation successfully and in a timely manner. The damage done to them is enormous but it’s so invisible and so hard to identify that they can never figure out what’s wrong with them. And they spend their lives feeling guilty for constantly failing at things and not even knowing why it happens.
