Answer:
PTSD
Explanation:
This is in my opinion, textbook ptsd.
The definition of ptsd is ,"The condition may last months or years, with triggers that can bring back memories of the trauma accompanied by intense emotional and physical reactions.
Symptoms may include nightmares or unwanted memories of the trauma, avoidance of situations that bring back memories of the trauma, heightened reactions, anxiety, or depressed mood." (Mayo Clinic, summarized by google).
If you break it down, this excerpt states exactly what Jerome is experiencing, therefore we can (very vaguely) conclude that this is PTSD.
