Planning for the past (what if my parents would do things differently?) is a sign of depression (not clinical advice). Blaming the parents is not productive and doesn't lead to solutions to the problems at hand.

For me, taking responsibility on deciding what needs to be done, how to get better at doing what needs to be done and how to get better at getting better, shifted the focus significantly.
