Is OTHER wrong in the post ? POST : There's a girl in my school who doesn't get along with many people. She's generally annoying and it seems like she tries so hard to fit in that she doesn't fit in at all. She also seems like a bit of an attention whore, as she's often loud and goes on about her gayness. I'm not homophobic. I don't see straight people bragging about their straightness so I don't want to see anyone doing the same.  

The other day, I was walking back from school with her (we walk the same way. I wouldn't if I had the choice, I'd rather walk alone.) and she started trying to talk to me about some real shit, to do with "depression" (multiple times she's been "exposed" for faking depression. There's little evidence either way, but it really comes across as fake) and I told her as nicely as I could that I can't help her.  

Today, she got mad at me for this. She says that no one else can understand her so I should try to help her out. However, even if she isn't faking - if she genuinely has something wrong - I simply don't care that much about most other people, including her. AITA?
