Maybe your parents got some things wrong. What you do with it from here is still on your desk.

Both things can be true: they handled something badly, and the repair is still yours to make. That is not fair, and nobody pretends it is. It is just how it works, because they are not the ones living inside your next ten years. Holding them responsible for what happened and taking charge of what comes next are not in conflict.

Pick one habit or belief you can trace back to how you grew up, and decide whether you want to keep it. You do not have to forgive anyone to do that. Changing one thing on purpose is enough for this week.
