Shawn, ADHD

Hi all, I'm new here but have loitered around the psych section on AO3. I've seen some fics written with the perspective that shawn fakes a lot of his personality, for various reasons. I'm looking, and hope someone can help me find, some fics which do the opposite. A fic about shawn and ADHD (or other things, like an autism AU), how that makes him who he is and how other people like Gus and Henry navigate that in loving ways. Or expand on stuff in the show, like how Gus claims Shawn on his taxes.

Any fics focusing on Shawn and Henry, where Henry is a good guy would also be nice, and fics where Gus takes care of Shawn.
