Hi, I am asking this for my friend. She is having nightmares about people. She used to like someone, but now that person is in relationship with someone else. It's been a year but she can't stop thinking about him. She is having daydreams and nightmares about him. This is causing negative effects on her daily life. She tried to keep herself busy, but it's all going into the void. According to my intuition she is suffering from OCD. Any kind of lead or help would be be appreciated.
