DEAR ABBY: I am a 16-year-old high school student. My friend "Denise" has an almost insane crush on a friend of ours. Denise is so obsessed with him that she has hysterical fits of crying and rage if he pays attention to another girl. She talks about suicide if she can't be with him.
I know this is not normal, but I don't know what to do. I'm concerned Denise will hurt herself or someone else. -- CONCERNED FRIEND IN CALGARY
DEAR CONCERNED: Tell your parents, a teacher, or a counselor at school about her behavior, her threats and your concerns. Your friend has gone off the deep end and may need to be psychologically evaluated.
