any type of mental/emotional disorder counts! no matter if it's diagnosed or not, you know your characters the best.
i have this boy who suffers of did, ptsd and other undiagnosed disorders :^(
Carver's got quite a bit of PTSD as well as severe anxiety/panic disorder :( After everything that's happened to him and his friends, he's.. actually fairly fragile despite being such a powerful person with very potent magic abilities.
Dude needs a hug and a nap, really.
Kiyoshi's diagnosed with depression, though it doesn't affect him that badly. And also, while it's not really a mental illness, he's got a huge fear of abandonment that can make him panic a lot at times.
i've got a few
i do everything to be as accurate as i can and avoid the mentally ill == evil trope like the plague (please tell me if i'm misrepresenting something!!)
My two main fursonas have disorders I have. Both have depression, generalized anxiety disorder, and PTSD. They
have others but its hard to go into it.
most of my characters have some degree of mental illness but here are the ones who i have "diagnosed"
John has something dissociative
Doc has autism and OCD. he has amnesia but it doesn't really count as a mental disorder because he did it to himself
Antares and Leif likely have PTSD
Feodor has depression
oh I have tons. Since I myself have (granted, they're undiagnosed) ocd, adhd & anxiety, many of my ocs do have those including my sona. I do have others who have things like ptsd, but apart from that the ones who have other mental disorders are more special cases than usual, like anorexia, tourette syndrome and all that jazz. I won't list everybody bc that would be wild but Pepper IC here is my gal with the most intense ocd showing and so I use her as my biggest ocd vent oc.
Calcifer has PTSD due to childhood trauma & abuse along with anger issues and a tendency to lash out at others. He's slowly slipping into depression due to his line of work and how he's treated.
While it's not explicitly stated in canon (and he's not diagnosed with anything either,) my psychology-friend and I think it's possible Micah may have undiagnosed BPD
Tycho has lived an immensely difficult life and, as a result, suffers predominantly from depression and PTSD. He was also diagnosed with autism as a child.
