Have you watched A silent voice recently or just crying over it after watching it a while ago? That one is really sad too T-T
For me, guilt like that just eventually goes away and then I'm just like, "Fuck it! I'm gonna simp over this character and not care what people think!" I mean it comes back sometimes but it goes away again then T-T Idk if you know this anime character but there's this character named Ban and he's literally thousands of years old but I still simp over him T-T even though he kind of has a crappy personality..I mean its not that crappy...But just a lil bit crappy T-T
