Welcome to WP! I think you will find some nice folk here.
And, with respect to your request...I found out at age 64 that I was on the Spectrum. And then the COVID-19 pandemic came around and I've been mostly staying home. (My age is just one high risk thing for me.) So, I've had limited opportunity to explore being an Aspie.
I can tell you that it was absolutely wonderful to find out. It explained so much. But, practical benefits? So far, not so much.
I was really hoping for one practical benefit: I was hoping that my medical providers could communicate more effectively with me. (I want stuff in writing and in simple terms.) So far, no luck. If you want to try your luck, then maybe start here:

And, I guess it might be a good idea to be careful revealing the diagnosis to folk. I guess strangers are fair game but I think--after the pandemic--I will choose to share the diagnosis only with folk who I don't think will be jerks about it.
But, honestly, I think my diagnosis is more interesting trivia than anything else.
Take care!
