In I Am J, J's mom leaves an envelope for him with Melissa. What does it contain?

In chapter 9 of I Am J, Melissa tells J that his mother has left an envelope for him. It's a large, heavy envelope—certainly much too large and heavy to contain a simple letter. J casually mentions that he thinks the envelope contains a parental consent form for testosterone. But it doesn't. Instead, the envelope consists of all the college application forms that J had left behind. Accompanying these forms is an urgent note from J's mom urging him to fill out these forms and write his essays, some of which are due at the end of the month.
It's not so much what's in the envelope but what isn't in it that really matters here. As well as there not being any parental consent form, there's no word about J's father, and crucially, no mention of those three little words that every child wants to hear from their parents: I love you.
