Self-preservation is a natural instinct to have.  It is a sign of self-recognition and self-worth.

—Some people even lack these components.  Unaware of the dangers around them, or unaware of their importance in the world.  These traits are often driven by their childhood nurturing, and socialization.  A more sheltered or more demanding life may rear different and sometimes unsatisfactory results… but I digress.

Self-preservation, like any other instinct, can be dangerous if anticipated or preemptively acted upon.  It can result in unnecessary loss or struggle that wouldn’t have existed had it been implemented in a more reactionary way.  Self-preservation usually stems from anxiety and fear.  Which should be recognized as unwarranted outside of situational moments.  It may be hard to separate fictitious stressors and realistic ones, when predicting future events.

It is normal to want to survive.  It is also normal to never address your survival outside of dire situations.  In all fairness, it is even normal to diminish your survival for any number of reasons.  However, I want to remind you not to go overboard.  Take time to analyze your own behavior, make sure they struggles you are facing are real, or at least real to you.  Make sure that the things that stress you out, are worth the pain and anxiety.  Make sure that you are mentally and physically to be making such drastic changes.
