Fortunately, as with many other diseases, medical science has developed effective treatments for depression. It is important to understand that treatment is usually necessary. Most people who suffer from depression have an overall feeling of sadness. They may feel hopeless and helpless and they may be very irritable. Adults who experience depression may feel an oppressive sense of guilt or fatigue.
Depressed people find it hard to think, work, play or love.
In other words, they can't enjoy life. They find it difficult to get out of bed in the morning or to fall asleep at night. They tire easily and may lose their appetites. Going out with friends becomes impossible. They withdraw from family and colleagues and become very isolated.
