Ignore it, deny it, and almost every undesirable woe seems to have some connection with doing so. Stressors may summate where the total sum of stressors lead to a suppression of the immune and endocrine system. Increased levels of cortisol have been dramatically linked to everything from memory loss to the destruction of selected brain cells. The summation and accumulation of so-called ordinary stress can lead to a helpless and hopeless attitude which itself negatively influences the immune system to say nothing of its potentiation of heightened anxiety or depression.

Stress uses energy.
It can deplete energy levels leaving one exhausted even upon waking after a night's sleep. From serious psychiatric disorders, including bi-polar and affective personality disorders, to simple acne, stress is a disrupter.

A strong desire to convey a favorable impression and marked insecurity about doing so. A fear of behaving in an unacceptable fashion.
