Answer:
Posttraumatic stress disorder (PTSD).
Step-by-step explanation:
Posttraumatic stress disorder is a psychological disorder that a person experiences after going through a traumatic event/ incident. This can affect people in all stages and walks of life, and there is no scale of the trauma that is specific for a person to have this disorder.
In the case of Tina, her inability to continue work, let alone get out of her home is an effect of the trauma that she experienced during the armed robbery. The event, though she did not get any bodily harm, left her with the recurrent images of the day, leaving her with a traumatic memory. Thus, she is likely suffering from PTSD.
