"I feel run down."
I'm all worn out."
Fatigue is a very common complaint people consult physicians about. It's a normal expected part of life. We all experience it. According to a medical source, fatigue is defined as "nonspecific cerebral perception of neuro-mascular sensations, chemoreceptor input and neural reactions to external stimuli."
Fatigue is subjective. It cannot be measured by clinical, objective diagnostic tools. It's hard to assess. In fact, the physical body can be weakened or susceptible to having symptoms when there is nothing wrong medically.
Ruling out medical causation or physical roots for the fatigue, that's where counseling and therapy can be of great help. Some questions can give significant insight in dealing with the problem of fatigue.
What problems or stresses are currently present in your life? How are you responding to those pressures? How much sleep do you get every night? What chemicals do you put into your body? How much time do you spend with your family or friends?
Many times, a change in focus will bring benefit of actually reducing or eliminating the effects or damage of fatigue.
