I think it was very apparent that Louise Gornall has experienced the mental illnesses that Norah faces in this book. I appreciated that she was able to articulate her experiences with mental illness for those that aren't able express their own experiences. She was able to let others catch a glimpse of what these invisible illnesses are and how they effect those who live through them and impact their loved ones as well. She showed that the irrational thoughts that accompany anxiety, OCD, and panic attacks can't just be quenched even with the most rational of ideas. 
 The ending of this book took my rating from a 3 to 3.75. I did not see that coming, and I thought it was an interesting way to take the plot. This story reminded me of Everything, Everything in a way, but was also really different. The only thing I was missing from this story is getting to know who Norah is outside of her illness.
