I'm such a skeptic............I read somewhere that she didn't go to therapy, so I don't know how she was diagnosed with PTSD. She also wasn't in the building that it happened, and I would think trauma being right in the name PTSD that that would be part of the it...........And, it's saying her best friend died. Do you ever see how many girls are called best friends by other girls on social media. They usually have 20 BFFs.
So, I'm not so sure you can say that this is directly tied to the shootings. It could be. But, I haven't seen anything yet that convinces me.............And, it's blown up so that people liked Exiled can make it more of an anti gun thing. (I'm not even pro gun, just anti media)
