It’s normal to experience problems and unhappiness at times. Different experiences can trigger temporary feelings of worthlessness, disappointment, sadness and self-blame; these feelings are normal and they usually pass after a short time.
Depression becomes an illness when these feelings last for several weeks, are severe and interfere with functioning in your day-to-day life. Depression has been reported by the World Health Organization as one of the leading contributors to the global burden of disease and will soon be the leading cause of disability.
Depression can change your old positive behaviours into new negative behaviours, however, it’s important to know there’s help available. It’s important to seek help as soon as you feel these symptoms progressing as depression can often recur.
