Silly oc lore (about Kate)

I want to yap a bit about character that I made with my friend.

Katarina aka just Kate is one of main characters from an project I make with my friend. The projects main idea is to comment on how person's art affects them. Kate is an artist who also likes to film things, through drawing she shows her feelings and thoughts. After Kate loses one of her friends her art starts to change becoming more abstract and deformed as her mental illness starts to show itself more. Kate's love toward filming and acting slowly starts to disappear as she slowly starts to lose herself. At the middle of the story because of Kate's paranoia she starts to blame one of her friends (Y) in her other friend's(Mel's) disappearance. Kate did not develop mental illness because of Mel's disappearance although Mel's disappearance did make them more upfront.
