My friend is an attention seeker?

my friend says she has depression, when she has NOTHING to be depressed about, literally nothing. she has family who love her, friends who love her, a good life with nothing wrong. she claws chunks out of her own arm when shes "depressed" and rolls her sleeves up so that everyone can see it and makes a whole show out of it. when i ask her what exactly she has to be depressed about she says she's depressed because her pets are dead and have been dead for 4 years (yeah she still cries about her dead goldfish) and that she was bullied in school but we're not even in school now we're in college. everyones bullied but you just get over it. now she has scars all over her arms it's revolting. i also wonder if she has something wrong with her as she says that a shark.. a lion.. a tiger, etc won't kill you and that they love humans. wtf? and she spent 4 hours crying because she saw a pigeon die and says that if she had the choice between saving a person and a pigeon from being hit by a car she'd save the pigeon.
