My 15 year old sister claims to be depressed by I think it's all just a joke. She made a friend a couple of months ago who was actually diagnosed with depression and I think she's trying to imitate her to "fit in" or whatever. I hear around that her other friends are starting to dislike her because she fakes these anxiety attacks. She's been skipping school often by whining to my parents and she's been really defiant and cuts herself too. My parents are worried sick about her and waste their money on a child psychologist when they're tight on money right now. We've tried begging I almost lost it but only ended up yelling at her for doing this to my parents. And I know she's not sad all the time because she's always talking happily to people she wants to impress but when it comes to her family, she's very rude. Is this just some edgy teen phase?
