<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing nightmares and flashbacks related to a traumatic event that I experienced a few months ago. I also feel anxious all the time and avoid certain situations because they trigger me. What could be wrong with me?  <response>: Based on your symptoms, it sounds like you might be suffering from post-traumatic stress disorder or PTSD. I would recommend some psychotherapy and mental health counseling to help you deal with your emotions and cope with your trauma. We may also need to perform a depression screen and conduct a psychological and psychiatric evaluation to determine the best course of therapy for you.
