Psychological disorders of all my classmates

For each of my old classmates at my high school reunion, suggest a diagnosis of their psychological disorder. Describe the disorder, and explain what symptoms led to your diagnosis.

Mark, who was the class clown,confides that he takes medication to keep him emotionally stable because he attempted suicide and tried to fly off the garage roof when he believed he had invented a nuclear umbrella.

Alice,the most likely to succeed, washes her hands repeatedly and dries them off with clean towels she has brought with her from home. This is her standard ritual. She will not drink the punch until she has done this.

The prom queen, Mary, is not at the reunion because she is afraid to leave the house.

The star quarterback, Gary, says that he is in charge if the CIA, and that a group of terrorists are planning to take him hostage. While he is talking he is carefully watching his wife dance with an old classmate and seems jealous.

Thank you for your time in answering these questions. I am comparing different diagnosis' for the same group of people.
