You Are Volunteering at a Psychiatric Ward for the Summer

You are volunteering at a psychiatric ward for the summer. On your first day, a man comes up to you and says you have very pretty eyes and asks your name. You thank him and give him your name.

After a week, you ask a doctor on the ward about this man, and the doctor tells you that the man suffers from:
