I'm not here to complicate any of this, but she was probably not shown the greatest example of 'family' - perhaps her mother was a decent influence in her life, and you most likely know how busy/absent her Dad was. She didn't have much balance in her formative years, and it's real tough to discover that balance as an adult. It's something somebody searches for their whole life, and sometimes you can't even know if you've attained it or not when you finally do.
It's easy to think "oh, they grew up a certain way - with a poor family setting, no normalcy (comparatively), etc, --- but with all the people they've known/watch on TV, internet/stories they've read....they 'should' have an example (or many) to follow". The problem is actually identifying that you are not on the 'best side' of being different and that you may need to change your life --- in order to even see those things as examples to begin with, to actually gain influence from them.
We are the blindest when seeing ourselves. Life is a real B. (for all of us, one way or another).
