I'm looking to find something that explores trauma/psychological themes but isn't super dark, something with a little light at the end of the tunnel. I'm currently browsing through psychological + slice of life but I'm not sure that's gonna lead me where I want. I can't really think of a good example either to help direct any recommendations. What sparked this sudden desire was ReLife actually, and thinking about Kaizaki's issues surrounding his neck being touched, and I got to wondering if I could find other manga's that deal with trauma in some way but aren't a total depressing mind f*ck (not that those aren't fun).

Thanks!

I'd suggest Aku no Hana, Annarasumanara, Bokura no Hentai, Eensy-Weensy Monster, Gisou Honey Trap, Heptagon, Houkago Hokenshitsu, In Full Bloom (YON Jae-Won), My Heart Is Beating, The Friendly Winter and Zebra.

Good luck 🙂

Not all of these deal with trauma, but they all explore various psychological and social issues in a less depressing/twisted fashion than usual:

Genkaku Picasso
Palepoli
Ano Ko no Ie
Goggle -- The title story.
Ame no Furu Basho
Anywhere But Here
Aoi Uroko to Suna no Machi
Black Coffee
Beautiful People -- Some of the stories in this fit, though I can't really remember which ones. The whole collection is worth a read, though.
Bouken Shounen
Haruka na Machi e
Shounenshoujo Ryouryuuki
Danza
Henshin no News
Ito Meguri no Sobyou
Kinderbook
Not so Bad
Sora ga Haiiro dakara
Sumikko no Sora-san
Yoru no Taiko

Seconding Annarasumanara and The Friendly Winter.

Inai Boku wa Hotarumachi ni Iru fits just about perfectly.

I'd also recommend reading some of Matsumoto Taiyou's psychological works. Maybe starting with Kanai-kun, or otherwise whichever plot most piques your interest.

Noragami
The main character is a victim of long term emotional abuse, and it is treated in a very realistic way. However there is quite a bit of humor as well. In fact it takes a while before one realises that the MC's humor simply exists to mask his hurt. Yet despite it all. YOu can't help but feel there is, as you put it, a light at the end of the tunnel.

Thanks everyone!

I've watched the anime for Noragami, do they diverge enough to warrant reading the manga?
