I don't mess around when it comes to OC torture. So... might as well put all of this under a tag.
Jordan was bullied his entire school life (from Kindergarten all the way up to his Junior year, when he finally dropped out); almost got murdered when his so-called "best friend" left him to die when he was attacked by an angry crowd; he still suffers from severe anxiety, PTSD, and agoraphobia because of this; and at one point later on in his life (when he's in his mid-20's) his mental state gets so bad he nearly overdoses to try and make the pain stop, only surviving because his husband got home early from work.
Jennifer was cursed to have all her friends die, so she refuses to get close to anyone, and the complete lack of relationships has made her depressed and slightly suicidal, though she hasn't attempted anything yet.
Jackson was homeless until he turned 18, but lived on the streets since he was only 10 years old after his parents died. He had no friends, thanks to severe social anxiety, and one day, after being very, very harshly rejected by the guy he had a crush on, his already poor mental state just plummeted, and he tried to end everything by cutting his wrist open with an old knife he found lying on the pavement near where he was staying in an alley. Thankfully, he was noticed by a passerby who just barely managed to save his life, but to this day his mental health hasn't gotten any better - though he hasn't tried to kill himself again as of yet.
Zero was relentlessly tortured and eventually killed for the sake of "science" after being ripped away from his family as a really young pup.
Zeke's parents died in a car crash, so he was sent to live with relatives who didn't actually care for him. They became increasingly neglectful and abusive over the years, (going as far to try stabbing him and breaking his bones on more than one occasion), making him terrified to interact with people. As if that wasn't enough, the only person he could rely on at the time - his boyfriend - was killed when his adoptive parents found them together and basically murdered him by smashing his head in with a rock. One of Zeke's wings was torn out shortly afterwards, and he was then locked in his room with no access to food - and limited water - for a solid three days. By the time the police showed up, after his boyfriend's dad called the cops after getting worried about him, he was in such bad shape from all the abuse, and not eating for three days, that he almost didn't make it. If they had been just a day later, he would have died.
Wes had a father who abused drugs and was verbally abusive to him and his mother. Later, after his parents divorced, his mother later turned to alcohol to try and "drown her sorrows" but it only made her mood worse and worse, before she become verbally abusive herself, and even physically abusive in some cases where she'd hit him or slam him into walls over nothing. Then he went out and got himself bitten by a werewolf, and then on the full moon, lost his girlfriend when he almost bit and killed her - and actually DID end up tearing an innocent stranger's throat out while he wasn't able to control himself or realize what he was doing. He still hates himself to this day because of what he did and has contemplated suicide on more than one occasion so he doesn't hurt anyone again.
Nick's uncle tried to sexually abuse him once, but thankfully he realized something was wrong before it even started up and told his parents to make him leave the house. But no, this story doesn't have a happy ending. Later, when he came out as bisexual, his extremely religious and extremely homophobic family immediately disowned him and forced him out of the home, not caring that he never was able to learn the skills needed to live alone. He lived in the cheapest apartment he could find, his (now ex) girlfriend being the only thing to comfort him... until she admitted she didn't like him anymore and was looking at some other guy Nick had never even heard of and broke up with him, meaning he was alone, having nobody that actually gave a shit about him.
