Post-traumatic stress disorder (PTSD) is a common mental health condition that can develop after a traumatic event. It involves symptoms like flashbacks, anxiety, negative thoughts and beliefs, hypervigilance and more. For more information visit the Cleveland Clinic's website. 

If you are not diagnosed with PTSD but feel you suffer from symptoms of it you should speak to your doctor or a mental health professional, such as a psychologist or psychiatrist. Make an appointment, and they will talk through the next steps with you, which is often being referred to a psychiatrist. This is so they can understand the best next steps to take with treatment and support.  It may be difficult to talk about the trauma. You may want to bring a loved one with you to the appointment for support and to help provide details about your symptoms and behavior changes.
