Dear Dr. Wolf,

Our 18-year-old son does well in school, has a part-time job, and is a kind, responsible person. He is planning to go to university next year. We're concerned, however, about his social skills and self-confidence. He has always been quiet and introverted, with just a few friends. He rarely goes out and prefers to spend time at home.

We've tried to talk to him about stepping outside his comfort zone, but he gets defensive. We're unsure whether there's something serious bothering him and whether he needs professional help.
