Questions
Rоger stаtes thаt he hаs been miserable fоr the past three weeks. He says he has been in an irritable mоod most of the time and keeps “biting peoples’ heads off over nothing.” He is also having trouble sleeping at night (he says he wakes up after just a few hours and can’t seem to fall back asleep). Roger has not been able to concentrate at work. He says for the past three weeks he has had a recurring nightmare that the house is on fire and he wakes up in a cold sweat. Three weeks ago, his house did catch on fire and Roger escaped but was burned on his legs and is undergoing treatment for smoke inhalation. Roger says he hasn’t felt happy or even calm for three weeks, but is always watching for something bad to happen. He has avoided going to his mother’s house for the past two weeks even though he usually went over there daily. His mom always has a fire going in the fireplace in winter, and Roger says he can’t stand to be around that right now. The times he has been unable to avoid her home, he said he felt nauseous as soon as he saw the fire, and that he began sweating. Unfortunately, everything he has done to avoid thinking about the fire does not seem to help – he can’t seem to help thinking about it repeatedly every day and he feels hopeless and sad as a result. Which diagnosis is most likely for Roger?
