Stress manifests itself in various ways

• Physical Manifestations: You may find that you are uncomfortable much of the time, suffering from headache, fatigue, sweating, or trembling. You may suffer from stomach cramps or nausea, or find you are always sick. The most serious physical effects include chest pains and heart palpitations, often mimicking the symptoms of a heart attack.
  


• Mental or Emotional Manifestations: Depression is probably the most common mental symptom of stress. More and more, people are seeking out treatment for depression when a few lifestyle changes might take care of the problem.
  
  Other emotional or mental signs of stress include anxiety, frustration, irritability, indecisiveness, confusion, loss of humor, short temper, worry, nervousness, or a loss in concentration or memory.
  


• Behavioral: Any sudden change in behavior should be a signal that something is wrong. Some of the behaviors that may appear as a result of stress include crying, yelling, throwing things, smoking, drinking, eating, pacing, or other nervous behaviors such as nail biting.
