Hi, DiamondGirl---nice to meetcha!! I was diagnosed well over a decade, ago, at age 47 or 48 (Asperger's under DSM IV). Finding out about oneself is sorta bittersweet---it was for me, anyway---because I was thankful I finally had an answer, but I was VERY angry that no one had told me before.
As for a support community: I think this place will be great for you---there's alot of us, here, who were diagnosed, well into adulthood; you're not different from most, here, it's about 50/50 (older and young). Maybe, just observe, for awhile---read everything (there's a specific women's forum, here), then, when you feel comfortable, enough, jump in!!
I hope it works out for you, and I hope you stick around, for awhile---we're glad you're here!!
Take care,
Cat
