I don’t think anyone can say they had a truly healthy childhood. I feel like there’s a baseline level of trauma that comes with the fact that you’re the legal property of someone else for your most vulnerable years, no matter how great your parents are, and this only gets exponentially worse for every degree away from perfect experts with principled objections to normative child abuse your parents are.
The simple presence of this factoid causes damage proportional to how aware you are of it at the time. I know that even if my parents had done things better, I don’t know how they’d reconcile the fact that my perspective always included thoughts such as, “I don’t have a choice because they are currently my life support”
