It generally occurs when a person is unable to function in social roles anymore, experiencing severe depression or feelings of being out of touch with reality. This often occurs after a long period of stress which has not been adequately dealt with.
This inability to function can occur in both work and personal arenas, resulting in difficulty in fulfilling obligations. It also causes the individual to develop physical, mental and emotional symptoms. A person experiencing symptoms of a nervous breakdown may feel extreme tiredness, weakness, episodes of uncontrollable crying, confusion, disorientation and feelings of worthlessness.
There may also be a loss of self-esteem and confidence, extreme weight loss or weight gain, disrupted sleep patterns and feelings of guilt and despair. In severe cases, an inability to move, called catatonic posturing, may result. This is a serious psychiatric condition and should not be taken lightly.

What Causes a Nervous Breakdown?
There is always a trigger or catalyst that sparks a nervous breakdown. Breakdowns usually stem from a change in a major life event such as a broken relationship, death of a loved one, a demanding job or financial difficulties. Factors that contribute to a breakdown include:
Stress
Depression
Drug and alcohol use
Genetics (family history)
Coexisting medical conditions such as vitamin deficiencies or thyroid disorders
