Watched Anohana but.... disappointed. Looking for animes with organic emotional gut punches.

I won't say I'm a sadist. The animes like Grave of the Fireflies, I wanna eat your Pancreas, Your Lie in April, were heavy to digest for me. These were the animes that felt organicallly sad.

Anohana felt similar to Studio Ghibli film 'When Marnie was There', the sadness seemed forced. Atleast it doesn't match my taste.
I wanna watch Plastic Memories, Clannad & After Story, Silent Voice next. Suggest few more animes that should make me sad.
