Any tragedy stories that made you sob like a baby?

Well it's not tragic but more like angst slice of life-ish 'Goodbye mom', it's a good work.

Ohh I don't mind heavy angst. As long as it's a good work and could make me cry I don't mind at all. I'll read this later thanks!

It’s really angsty but well written and not romanticised
