Does anyone else feel overwhelmed by the massive amounts of literature and different editions and such that you get sad and end up reading nothing at all?
Yes, sometimes. Not just literature though. Everything.
Try dedicating yourself to a specific genre or nationality of literature. Say to yourself "I will read every seminal work of Hungarian literature." Buy all the books and do it.
It won't feel like you're reading one book in an ocean of books. It will feel like you're putting together the pieces of a puzzle that is that nation's literary culture.
