The Semi-colon Project? U know that?
Anhways, think about TWD (The walking dead) and how many of them have/are suffering mentally both because of the apocalypse and after
-Carol (abusive husband, dead biological daugther, multiple dead children that got attached to her - henry, benjamin, mika & lizzy, sam) (did i miss any children lol)
-Daryl (abusive dad, horrible brother, horrible childhood, need i say more?)
-Beth (cut her wrists and contemplated suicide during season 2, dead brother? Kinda forgot but you get the point)
-Bob (idk man, just seems like he'd contemplate suicide after being in two different groups that fell apart and left him the only alive member of both groups)
-Andrea (seems to have had experience either calming down ppl with issues or has contemplated suicide too off screen/in comics, cuz how did she know to let beth make her choice instead of forcing her to do stuff?) (Idk, just a guess)
-Noah (idk, being trapped in a hospital and forced to work there and be mistreated for who knows how long? Also being there when tyreese get killed maybe?)
-Ezekiel (i dont think the tyroid cancer was in the comics but i feel like he's suffered from suidical thoughts before maybe? Just a feeling)
-Abraham (dead fam, did contemplate suicide on screen)
-Eugene (i suspect he had family issues, idk it feels like that but he definitely have self worth issues)
-Lydia (probably? Horrible mom, dead dad, grew up during the apocalypse)
Damn these are just making less and less sense
Anywho, these are just some thoughts i had so maybe dont take them too seriously
