The CDC lists the following as risk factors that increase the likelihood of a person committing suicide:

• Previous suicide attempt(s)
  
• History of mental disorders, particularly depression
  
• History of alcohol and substance abuse
  
• Family history of suicide
  
• Family history of child maltreatment
  
• Feelings of hopelessness
  
• Impulsive or aggressive tendencies
  
• Barriers to accessing mental health treatment
  
• Loss (relational, social, work, or financial)
  
• Physical illness
  
• Easy access to lethal methods
  
• Unwillingness to seek help because of the stigma attached to mental health and substance abuse disorders or suicidal thoughts
  
• Cultural and religious beliefs—for instance, the belief that suicide is a noble resolution of a personal dilemma
  
• Local epidemics of suicide
  
• Isolation, a feeling of being cut off from other people
  

Now, don't those risk factors cover just about every person in the U.S.of A. if not the world? And if an "unwillingness to seek help because of the stigma..." is a risk factor, perhaps the CDC should add another factor to their list, namely:

• Unwillingness to seek help because of the risk of being drugged and incarcerated against one's will.

Not having access to the resources required to study suicide 'scientifically', I can only guess as to how many people have killed themselves because they did not want to lose control over themselves the way a person loses control when he is the object of a forced intervention. But I do know that there are people who have done that. And until the Mental Health Profession is willing to explicitly examine the ways in which it actually encourages suicide, it is going to fail to fully understand the reasons why people suicide.
