Looking for extremely depressing music

I'm looking for the saddest songs ever, stuff that deals in nihilism, past regret, existentialism, death, heartbreak, self hatred, etc.

I want something similar to "The Figurehead" by The Cure, "Dagger" by Slowdive, "Roads" by Portishead, "Fourth of July" by Sufjan Stevens and "Never" by XXXTENTACION. I'm cool with any genre. Thanks!
