They all state that the disability has to begin before the 18th birthday (aka diagnosed). What, should I lie and say that it was?

"To be eligible for services, a person must have a disability that begins before the person's 18th birthday, be expected to continue indefinitely and present a substantial disability as defined in Section 4512 of the California Welfare and Institutions Code. Eligibility is established through diagnosis and assessment performed by regional centers."
If that's the place you mean, you can definitely use the regional centers, and it wouldn't be a lie at all. Any form of autism begins before the 18th birthday by definition. It doesn't matter if you're diagnosed at 8 or 80. It's just putting a label on what has already occurred. Autistic behaviors don't retroactively become autistic after a diagnosis; they always were.
I've gotten services with a "begins before 18 (or 21)" requirement, and I was older than you when I was first diagnosed. Now, go get the help you need and deserve.
