John C

John has type one diabetes but refuses to be diligent about checking his blood sugar, or taking his insulin. A social misfit and an outcast for many years, John wants to be considered a regular guy, and pretends to be one by eating whatever he wants without regard for his illness. He has been in a near-coma and hospitalized multiple times. His parents want to stop enabling his self-destructive behavior, but won't kick him out of the house because they fear he'll die without their supervision.
