Welcome! I hope you like it here.
And, personally, I suspect that if you do not have some compelling need for a diagnosis then you might be better off without it...for a few decades.
If you get the diagnosis now then people will likely judge you based upon it. And some things might become unavailable for you. (For instance, one of the best things I ever did for myself was being in the U.S. military. It looks great on my resume and there are Veterans' Discounts.)
Without a formal diagnosis they'll just think you are odd. But they won't refuse to hire you because you are Autistic.
Then, when you are better-established in life, you can...if you choose...pursue a diagnosis.
Maybe don't wait as late as I did, however. All my life people thought I was odd or weird but the word "Autism" wasn't mentioned. (In part, because diagnostic criteria for it wouldn't have applied to me until I was 40 years old! Before that, they hadn't gotten around to writing the diagnostic criteria that would apply to me!) So I went through life just being "weird". It was not until I was 64 did I discover that I was Autistic. And it was only through chance that I got assessed. I almost missed it!
