I need sad book recommendation

Hey guys. So here is the thing. I have read " You've reached sam" by Dustin thao and cried my eyeballs out. Like I was ugly sobbing . But after that, every sad or emotional book which I read just didn't make me feel that much. Like u was meh or " oh its sad" and that's it. Like I need a book which would wreck me . Like I want a book which will make me sob as ugly as I did while reading " you've reached sam" . So please guys help me out.
