I’ve searched all day in the forum for a fic where Dean and Sam are young and whenever Sam and John fight, Dean has a panic attack because he can’t hear them and he can’t follow what they are arguing about. It really frustrates him. On one occasion Sam and John apologize to Dean.

Edit: I found it myself. Only took a few days but it’s “And So It Goes” by superchester.
