The Fault in Our Stars Chapter 18 Summary

Hazel wakes up at 2 a.m. to see that her phone is ringing.
She's immediately terrified that Augustus has died.
When she picks up, though, Augustus says he needs her help. He's at the gas station and his G-tube is messed up.
He doesn't want to go to a hospital and just wants her to come help him.
So she gets up and takes the car.
When she gets to the gas station, she sees that Augustus is inside his car, that he has vomited, and that his G-tube looks totally infected.
Hazel knows what she's gotta do: she calls 911 and waits for an ambulance to come.
He starts to say that he hates himself, that he hates all of this, and that he just wants to die already.
Hazel stays with Augustus and recites a poem to him as he loses consciousness.
