How does Jam behave during the first 2 chapters?

A good deal happens in the first two chapters of the novel. In the Prologue, we learn that Jam has had some sort of trauma in her life that has put her into a deep depression. Jam says that her boyfriend, whom she had dated less than two months, died. Then we become aware of some strange things that indicate there may be a twist in what actually happened to Jam. First, notice that on her application to The Wooden Barn, Jam’s parents wrote that she was suffering the effect of a trauma, as the reason why Jam needed to attend the school. Second, there is no mention of a death even though that is the reason that Jam says she was sent there. Third, when Jam shares the way her friends treated her after the death of her boyfriend they don’t seem very sympathetic. In fact, they seem almost callous. Jam mentions that one of the girls suggested Jam needed to “get over this already” (p. 11).
