You may want to speak specifically about the behaviors that have raised your concern so that both you and the student share the same frame of reference about the situation. Most importantly, by speaking directly, you convey your respect and caring for the individual. Except in emergencies, it is important to present your concern in such a way as to enable the student to freely accept, consider, or refuse your recommendation. If you would like, you may use my telephone to call the Counseling Center to schedule an appointment. I'd be glad to walk over with you, if you would feel more comfortable.
Counseling can help.
Some people need time in order to think over the decision to seek counseling. A caring and gentle suggestion is usually enough.
