Scouring the internet for this fanfic

It’s been years since I started reading this HP fanfic but couldn’t find it for the life of me.

Can’t recall if it was in ff or ao3. This is a harry whump story where he is abused by the Dursleys. Harry can sort of like see magic like floating circles or something. Vernon is trying to beat the magic out of him. Then there’s a scene where he chains Harry in the basement and makes him drink holy water to cure him. Surprisingly it seems to work since Harry stops seeing magic.

Hoping someone has read it too and help me find it.
