Depression doesn’t mean just feeling sad. Nowadays, however, depression is often misused to describe normal, temporary feelings of sadness, grief or disappointment. Depression is an extreme low mood that lasts at least 2 weeks in which someone feels extremely sad and hopeless, with lots of negative or self-critical thoughts. Their energy levels are reduced and their sleep, appetite, concentration and memory may all be affected. They might feel irritable, and often, particularly men with depression, might appear to be angry, rather than low.
Like all mental health problems, depression is caused by a combination of different factors including an individual’s genes, the influences of early life experience, current stressful events, and one’s internal coping style. The triggers for depression can be different for different people though often they are related to some type of loss (such as a break-up, bereavement or academic failure) or traumatic event (such as sexual or physical assault). Sometimes people find depression might occur completely out of the blue.
