Self diagnosed autism is not valid

I keep seeing this all over my socials, but fuck that, self diagnosed autism is not valid. It doesn't matter, if you were not diagnosed by a licensed doctor, you cannot just call yourself autistic. I was properly diagnosed when I was 5, regardless of your circumstances or your upbringing, it's fucked up to call yourself something, or especially "diagnose" yourself when you haven't been to a doctor. And that goes for everything, especially autism. Go to a doctor or fuck off, autism isn't some trend.
