Well, I probably can't give much advice, but I can be an understanding friend to any fellow aspie (should that be a proper noun, Aspie?) within driving distance of Birmingham.
I wasn't officially diagnosed until 2015 at the age of 63. It means that I've developed all kinds of weird strategies of dealing with it over the years, but only now understand why they were necessary.
Send me a message and I will reply with email address and phone number - any more is up to you.
I have several good local coffee shops and bars including veggie, vegan and several Wetherspoons (Who have a policy of NO NOISE at all other than the conversations of others - not even till beeps, piped music, etc.)
