https://www.mangago.me/read-manga/warehouse/ got me SO depressed... i wasn't satisfied with the ending though, too unrealistic. still worth reading
If you like really heavy, plot driven, complex, & somewhat angsty & depressing story, try Sora's Eyes. It won't get really depressing until after 3/4 of the entire series, with the death flag constantly hovering on either one of the 2 MCs. It took that long for the series to build up the tension that just exploded toward the end. But at the end of the day, what really gets you is the selfish wishes of a dying person who is just so love sick for another, that he'd do anything to be with that one person until the end, and yet too afraid & proud to be honest with his own feelings, that he'd just drive himself to a corner every time. It's a human's weakness that a lot of people can relate to, & that's what's making it so heart-wrenchingly depressing.
