Summary: OCD - Obsessive Compulsive D ? = Disorder or Dysfunction. It's both.
People on a individual basis or within a group display the same instances.
A lot of people are candles in the wind when it comes to group behavior.
Few think with their own minds and feel with their own hearts.
The main result of unhealthy OCD is cognitive dissonance and a flip flopping of the personality.
Un-grounding us in a way that makes us unpredictable and untrustworthy, especially to ourselves.
This part of our personality makeup is the hardest to harness and decipher. It also comes with the greatest rewards should you discipline yourself to recognize, arrest, and correct inappropriate or unhealthy instances.
Certain individuals in my life are very much this behavior to me. They cant just walk by. At first it confused me as to why. Now I only need wait and then the reasons come to the surface, as no person is able to hide their true motivations. The behaviors they display uncovers them in the most raw and at times the most uncomfortable way.
Dare to be different . Will result in a lot of OCD towards you. Some of us count on it.
