There is nothing wrong with your son. He doesn't have any syndrome. Patients with Autism can hardly speak, let alone get "90s" in all their classes. Your snowflake diagnosis to make your child "extra-special" is an insult to parents struggling with profoundly, permentantly, disabled offspring, an insult to your son whose natural condition wasn't enough to make you happy with him, and an insult to the intelligence of the rest of us who can see right through this ridiculous bullshit.
You are raising your son to be a sperg. Stop. You've done enough damage already. Get him a normal childhood in the time he has left. Otherwise he'll end up a mendacious, amoral, flake like you.
Autism is a spectrum and not everybody is the same.
I have an uncle who is profoundly disabled, like one-of-the-most-disabled-in-the-world-can't-speak-or-toilet-himself disabled, and it doesn't insult his parents or any of his relatives when another parent struggles to find the right care for their child's health. Doesn't matter if it's autism anywhere on the spectrum or a speech impediment or full-blown AIDS.
