PTSD

Post-traumatic stress disorder (PTSD) is an anxiety disorder caused by very stressful, frightening or distressing events. Someone with PTSD often relives the traumatic event through nightmares and flashbacks, and may experience feelings of isolation, irritability and guilt.

Season 2 is the only season where PTSD is mentioned, as Adrianna had been diagnosed with it sometime during the last few years.
