Faith's friend, who is a 16 year old girl, named Grace met up with her one day. The next day, Faith saw her in the store and wen
t up to her. Her friend didn't know who she was, and was completely different. She said her name was John, and that she was a 22 year old man. Why did Grace do this?
Grace has what is called <span>Dissociative identity disorder, or multiple personality syndrome. When you have this condition, a person can change from one person to another (in their mind), and they can't remember anything about the other personality.
Hope this helps! (Can you please mark brainliest? </span>Thanks!)
Explanation: PTSD is a psychiatric disorder that occurs to people after a traumatic experience. Since Sam survived a very bad car crash, he is traumatized and should seek professional help.
