PTSD and Need of Counselling and Therapy.. Contact us at 9872880634 in Chandigarh. Post-traumatic stress disorder may occur after a person experienced a severely traumatic event. He or she may relive the experience in his or her mind which causes stress & anxiety. If a person with PTSD comes into contact with stimuli (any object, person, or situation) that he or she associates with the traumatic event, he or she may literally re-experience the event by crying uncontrollably, panicking, or losing control. Subtle symptoms include insomnia & avoidant behavior. PTSD may manifest itself immediately after the traumatic event or even years after.
