what happened to ponyboy after dally died ? what was he worried about when he woke up ?

Ponyboy passed out after Dally was killed and ended up in the hospital. He slept for about three days, suffering from exhaustion, shock, and a minor concussion. When he woke up, Soda told him that he'd been sick...... his response, "Is Darry sorry I'm sick?" He also worries throughout the chapter that maybe he didn't ask for Darry while he was delirious
