It creeps in when we feel the nature, duration or circumstances of a situation are outside our control. With the death of a loved one, the birth of a child, a job promotion, or a new relationship et al, we experience stress as we readjust our lives. It is the insidious, low-grade stress that gradually erodes health and performance. The weight of real or perceived threats builds up to a point where home, work and social life are blighted. In so adjusting to different circumstances, stress will help or hinder us depending on how we react to it.
Every human being is potentially vulnerable to stress.
No one is bullet proof. In other words, stress is endemic in all our lives. It is a life circumstance, not a pathological condition. Some feelings can be signs of stress too. Your body and emotions are attempting to give you a message and you need to listen to it and sort it out.
