Soul-Crushing anime that's only 1 season long

This probably get's asked like every day but I want an anime that will make me sob uncontrollably, basically. I've already seen (and loved); Cyberpunk: Edgerunners, Akame ga Kill, Devilman Crybaby, Angel beats!, Charlotte, Terror in Resonance. I'm basically looking for more stuff like this, especially ones that are so sad because of 'love,' like Cyberpunk Edgerunners, Angel Beats! and Charlotte.

I also already have No. 6, 86, Attack on Titan, Erased and 91 Days on my list (which I hear are sad). I know there's probably not a lot of shows that fit the criteria that I haven't already listed but any recommendations would be greatly appreciated!
