“I would never slay the dragon, because the dragon was also me.”
I am going to be honest and say that the way Aza's OCD and anxiety is potrayed is completely on point and genuine. I can actually see her struggling through it, how even after fighting it so much, anxiety takes over her mind and makes her question her every move. That was something I could relate on some level, and I really appreciate that John Green has wrote about it in a very realistic way. You can actually see how hard Aza is trying to fight it, but then comes a point when even she cannot control her thoughts no matter how much she tries. It was all just too real and heartbreaking to see how something so small, just a couple of thoughts then becomes something more than what a human mind can control.
