Congratulations, but not everybody is capable of reaching that conclusion on their own. Like you said, having good parents is a huge part of it. Good teachers too. But some conditions, like depression, bipolar and others, include low self-esteem or excessive self-blaming as a symptom, which in many cases totally precludes reaching the same conclusion as you unless a grown-up tells the kid that what's going on isn't their fault.

Now, if the grown-ups are actively calling the kid out for behaviors that are the result of an unmanaged condition, the prime example being a kid with ADHD or ADD who has trouble paying attention in class, and especially if they're assigning negative traits to the kid based on those behaviors, such as telling them that they're lazy or antisocial, then they're just making everything a lot worse and that kid is likely to self-blame for years, even after receiving a valid diagnosis.

Well, I did so too, and it worked really well, until now, where I am a dad with a 6 year old son, where suddenly the positive attitude wasn’t enough, where I suddenly realised how much my partner is doing so can have positive attitude, how much I was just ignoring and laughed away, how much I just actively tried to forget subconsciously, or even consciously, how much luck (or hidden support) I needed to get where I am, and how fellow neurodivergent individuals didn’t had it and have major struggles in live now, and how easily I could have ended up like them 🖤 Stay save, positiveness is great, but don’t ignore darkness too much, or it will hit you while you are not prepared, and then it will hit you hard
