Killy asked a question

Anyone can recommend me a sad manga/hua/hwa that isnt really about romance but more of a slice of life(?), or let's just say doesn't have romance as the main focus, but instead about a teen/young adult (preferably a teen is possible) that is going through depression mainly developed because of their family or it developed by itself, and now this teen is all alone in this, where no one can understand them, and possibly think everyone is against them. In few words a very sad angst dramatic story lol
