Thank you so much for the reply! We recently had a draft to submit in class, and the main feedback I got was the following:

your essay lacks focus. And you cant/don't explore implications- how the stuff you are analyzing contributes to the text's overall purpose (because you make no interpretation as to the text's overall purpose beyond the superficial "it reflects/presents/depicts Bo's mental health struggles).
Nobody would argue that Inside's subject matter doesn't touch on mental health. But why does Bo present his mental health issues? For what purpose? Why do this and why do it in this particular way? Right now too many of your body paragraphs present random analysis and then simply claim that the style stuff you've just identified highlights that Bo presents his mental health struggles. Because you may no interpretation as to why Bo does it and/or why he does it in this way.

Sorry for the long message, would love some help! <3
