A long list of politicians and rulers throughout time have had mental health diagnoses.
At some point, most of us will suffer from stress, anxiety and/or depression. These often come with changes in ones life; i.e., moving, childbirth, a new job; or from financial troubles, the loss of a job, friend or family member. This may be how mental illness starts out, but with proper treatment and/or medication, life returns to happy contentment again for most.
For others the symptoms are worse and mental health can be a life-debilitating event. The severity of the illness can affect not only the people themselves but their family, their ability to work or go to school, their finances, and the ability to function as they once had.
