i think most people who get too engrossed end up like this tbh
the few girls i knew in high school that cosplayed were very weird and moody.
edit: one of them ended up doing n00d cosplays of something (she claimed it was artistic or something) and she ended up turning into a blind political advocate for liberals (i only say this because I know she failed the ontario literacy test in grade 10, misspelled many things on fb in her rants because she was so angry when she ranted, and if anyone refuted her arguments she would block them, and at one point she posted a satirical online news piece and thought it was real)
That's a bit sad to hear - I always wondered what most cosplayers were like, since I haven't met any in person.
