We generally use the word "stress" when we feel that everything seems to have become too much - we are overloaded and wonder whether we really can cope with the pressures placed upon us.
Self help for treating stress
Exercise - exercise has been proven to have a beneficial effect on a person's mental and physical state. For many people exercise is an extremely effective stress buster.
Division of labor - try to delegate your responsibilities at work, or share them. If you make yourself indispensable the likelihood of your feeling highly stressed is significantly greater.
Assertiveness - don't say yes to everything. If you can't do something well, or if something is not your responsibility, try to seek ways of not agreeing to do them.
