Mental Illness — the lack of love causing the failure to bond, causing separation from self and others, causing automatic reaction of fear/flight and delusion of inferiority in the gentle nature and and anger/fight delusion of superiority in the proud nature, causing failure to adapt and acquire the self-abilities, remaining dependent of others for the vital need of love. Prevention and Cure — love empowering bonding, empowering self-acceptance and adoption of self-abilities — self-esteem, self-examination,  self-knowledge, etc., changing from the physical oriented, naive, child mind to the nonviolent, self-control, self-love,  cognitive perceptive, self dependent, adult mind. Dependency on psychiatric drugs, just like with alcohol or illegal drugs, guarantees the person cannot develop any of the self abilities, including self dependency, guaranteeing suicidal and homicidal hopelessness.
