I remember finding a really good Harry Potter fan fiction. It’s a Harry/Draco ship (Drarry), and it starts off with Draco finding Harry after a breakdown, unable to tie his shoes. I believe it was on archive of our own but I can’t remember
This seems to be Sensitive Touch by Raserwolf:
When Draco Malfoy encounters a struggling and frustrated Harry desperately trying to tie his shoes after a meltdown in the Great Hall, his curiosity regarding the incident leads him to seek the help of the two people closest to Harry: Ron and Hermione.
