I recently had a revelation that neither of my parents were "good" parents. But also realized who my first two "good" parents were. My dad's mental illness turned into psychological abuse and he eventually committed suicide. Luckily, my mom married one of my "good" parents and we currently have a great relationship.

I have two older sisters, one turned out fine. She was born resilient, and didn't really seek a foster. The other sister is a different story, and I had wondered if she had found a "good" parent as a child.
