Research indicates that ongoing difficulties, such as long-term unempolyment or living in an abusive or uncaring relationship, are more likely to cause depression than recent life stresses. Depression can also run in families and some people will be at increased genetic risk. However, this doesn't mean that you will automatically become depressed if a parent or close relative has had the illness. Life circumstances are still likely to have an important influence on your chances of becoming ill.
It is also common for people to experience depression and anxiety at the same time.
