What is the opening line from john green's the fault in our stars?

The opening line of John Green's "The Fault in Our Stars" is, "Late in the winter of my seventeenth year, my mother decided I was depressed, presumably because I rarely left the house, spent quite a lot of time in my bedroom, read the same book over and over, ate infrequently, and devoted quite a lot of my abundant free time to thinking about death." This line sets the tone for the novel, introducing the protagonist, Hazel Grace Lancaster, and her struggles with illness and existential thoughts.
