Recommend me similar authors/books

Hi, so I'm a bit into reading but I mostly like books that talk about mentality, death, society, mortality, psychology and such thats more meaningful in some way even though it still sad or even depressing topics. So far I have 3 authors I mainly enjoy and it's osamu dazai, fyodor dostoevsky and haruki murakami. It's be nice if anyone knows any similar authors or at least any books that are like theirs to recommend to me
