How can someone I've known for so long turn on me like that?

I would like to see her go through all that shit, and come out on top, just like she was before.

I would like to see her try to even grasp those problems in the first place.

She does not even have an inkling of what has happened to me, and yet my best friend still judges and laughs. Nobody tries to understand anymore.

It's just a lost cause.

I don't care enough to go after this. 

It's not my problem anymore.
