Hi. I have a friend who has had a crush on a classmate in high school, for 4 or 5 consecutive years. She buys his laundry detergent, so she can smell like him, and although she likes him, which is an understatement, she will not talk to him.
She has been creeping on him for so long, and will not let it be. How do I convince her that she has a problem and needs to seek mental help?
