I have this for the toxic part and although it does have some recovery, it's still a pretty upsetting read... I really do recommend giving it a try, though. https://www.mangago.zone/read-manga/monster_child/
There's also one that I can't remember the name of, it was a story about a former delinquent and his deaf class comrade who's always injured (for reasons I won't spoil). I'll need to wake my other computer up for that one so if you haven't read it yet, tell me so I can see the notification and remember to search for it ;)

Hello! Could someone recommend me a manhwa where the story focuses on and starts off with a MC living in a toxic environment where everything is depressing (like parental issues, school issues, work issues, mental health issues) and we journey through their experience as they slowly recover? But they keep hitting obstacles that bring them back down or their past is chasing them. And the MC has an aggressive/rude personality. Or the MC could have a lifeless/hopeless personality. Also maybe some trauma bonding with friends they meet along the way.
