Question:

WHY ARE CREATIVE PEOPLE SUSCEPTIBLE TO DEPRESSION?

Answer (from some doctor..lol):
it may be that some mood disorders foster creativity or it may be that the lifestyle of creative persons is more likely to lead to depression. On the other hand, a third
variable may be responsible for both a person’s creativity and increased vulnerability to emotional disturbances, and thus there may be no casual link between creativity and mental illness.

hm..interesting.
