Depressing books written in first person, any suggestions?

So I just read Sarah Kane's 4.48 Psychosis and nearly cried my eyes out. So I'm looking for books just like it. In a way, Ottessa Moshfegh's My Year of Rest and Relaxation, The Bell Jar by Plath and The Catcher in the Rye by Salinger are also good examples of what I'm looking for. (Also, in a weird way, Dennis Cooper's The Sluts)

Basically the characters talking about how much life sucks, they have nothing to look forward to, everyone hates them, etc etc Whether it's a novel, poem, autobiography, or something else, it doesn't matter as long as it fits the bill

Thanks in advance.
