I think any extreme in one direction (shaming of your sibling, for example, Rose) means there has to be a gap in education the other direction (teaching good self-esteem habits). It's kind of like the children we all have seen who appear to be "brats" because their parents never say no? If we were abused, we learned certain things because we did not have any way to check them out but, having learned those incorrect things that come with abuse, we obviously didn't learn the opposite, "good" skills because our parents didn't know those to teach them to us and, likewise, we usually did not have any way to acquire them.
