I recently made a a doomed yaoi list that pretty much will give you enough trauma to last you several lifetimes so here’s the link: https://www.mangago.me/home/mangalist/3996573/
I hope this helps(づ ̄ ³ ̄)づ
off the top of my sleep-deprived head, but maybe you've alr read these:

Do you guys have any recommendations for yaoi/yuri where the MC has mind paralyzing trauma?
