8. Jim Carrey
The well-known comedian and actor, Jim Carrey was first told by doctors that his role in the movie “Me, Myself, and Irene” suggest that Jim is suffering from a split personality, and he can be violent at any point of time, on any issue. Later on, Jim Carrey himself declared that he is a victim of depression from his childhood due to some family problems. His anger and aggression on many issues in his early years clearly attributed his personality to be a prey of bipolar disorder. Well, it is really poignant to know that the actor, who makes others burst into laughter, is himself so dismal from inside.
