We are on a road to significant life disruptions when we cling to what we wish the world was like instead of what it really is like. As M Scott Peck wrote, “Mental health is an ongoing process of dedication to reality at all costs.”
Like it or not, we are all neurotic to some degree. If the wrong set of circumstances comes along, and if they are combined with unhealthy attitudes encouraged by poor parenting and genetic tenancies, any of us can tip over into the abyss.
Mental clarity is fundamental to emotional health. That's why, despite the biological component to mental illness, our therapeutic approach should be holistic and address cognitive issues. A cognitive-focused approach has a history of greater effectiveness than drugs (except when dealing with extremes psychotic breaks, schizophrenia, etc).
After an initial physical exam rules out disease and general illness, an eclectic approach that is focused on cognitive therapy, is the preferred direction. For most issues, drugs are best regulated to use as a tool allowing a person to find a place of stability in order deal with the fundamental unhealthy cognitive issues.
