"I just wish I was fucking dead".
Overheard by complete chance while wandering the corridors during a free period. Turned right back around and took the long route so I wouldn't have to walk past the classroom. It was a bit of a broken pedestal moment for me, but I never told anyone else about it.
The teacher who said it was one of our most beloved History teachers, who we later found out had been stopped from committing suicide at least twice by one of the Deputy Heads (who'd been friends with him since their university days) in the past. Not stopped as in "talked things out and convinced him it wasn't the best way to deal with his problems", but as in "physically picked up and dragged away from the window". He (the Deputy Head) was quite intimidating as a teacher, but we gained a lot of respect for him after learning that.
