I Picked Up a Bunch of Men

Looking for Someone Kind Enough to Help Me Find a Book

I'm looking for a novel. I think in the story, the protagonist has to experience intense emotional upheaval in the real world to wake up. Then the System sends him to different worlds. It's an angsty story, and it's so heartbreaking that even I, who love angsty stories, was afraid to keep reading. I want to read it, but I can't find it.
