Korra struggled to recover, suffering from post-traumatic stress disorder and being haunted by flashbacks to her encounter. Although she recovered physically, her emotional struggle led her to embark on a journey to reconnect with her Avatar Spirit while hiding her identity as the Avatar, going against her tendency of being prideful about it. The evil spirit that drove Korra crazy. It is very sad but at the same time strength and power. Korra's mind is disconnected from her body; her physical recovery is slowed down by the internal struggle that rages in her mind as she tries, and fails, to process her trauma. Flashbacks, nightmares, and severe anxiety are all common symptoms of PTSD, and this holds true for Korra throughout the season, as we see her plagued by flashbacks of her near-deadly encounter with Zaheer.
