My sister aged 20 years has been molested and groped by house owner 18 days back. Since then she is having nightmare every night with some horrific scene which depicts that something more dangerous going to happen with her. She is frightened and not able to concentrate on her studies and personal life. She is completely shattered and lost her control. This moment she becomes normal and the next moment she starts crying or becomes angry. She also feel some kind of pain in the head and the body temperature gets increase suddenly. We are completely confused about her recent behavior. Can you please suggest some ways to overcome this nightmare situation?
