My sister acts like a mature girl when she?s in the stable state but suddenly she gets hurt so easily & start acting like a kid, she doesn?t like going out, talking to people, she hates the light and used to switch off light whole day if we on the light she gets irritated. She gets very easily emotional and starts telling about her incident to everyone, she cries most of the time and while crying she acts like a kid. She never behaves such a way in front of anyone she does those things alone. When she gets angry she starts hurting herself. Nowadays she forgot thinks, she can?t recall things easily, earlier she was very quick and intelligent. She has gone through so much incident from her childhood, started behaving this way from last 1 year. And no one is with her to take care, even when we try to make her understand she thinks we?re wrong, she?s not even sexually okay. Is something serious what?s happening to her?
