I see your point. Counterpoint: have you actually read the post? OP’s post reads less like “this is why we shouldn’t have kids” and more “holy fuck am I gonna be able to have this kid grow into a functioning adult?”. You can at least stand to be less rude.

OP, I’ll toss you my two cents as a slightly younger person whose been diagnosed their whole life: if you’re this worried about being a good parent for the kid, then I honestly think your kid is in the best possible hands. I think the biggest thing that helped a lot for me growing up was patience - I was lucky enough to have parents that loved me enough to have the patience of a saint. I also think I didn’t speak til I was around 3 or 4, but nowadays I am able to actually hold conversations with people, have a full-time job in IT after graduating college with a bachelor’s, and I am able to live on my own without assistance. While that’s one part a humblebrag, I also two parts pointing that out because your kid can also achieve the same things - if a mess of a kid like me can do it, I optimistically believe that anybody can do it.

Now, gonna be real here: it’s not going to be easy, doubly so because you’re also diagnosed yourself and a single parent. It’s not impossible, but you will go through a lot of trials and tribulations - and so will the kid, because they also have to put in the effort. But if you love that kid, give them the patience they need, and try your damnedest to help them out with anything they need growing up… I think that sounds like a good recipe for raising any kid, autistic or not.
