Clinical depression is not about feeling sad, bereaved are overstressed. Is characterised by a persistent low mood, a lack of energy, difficulty with concentration and memory, and a lack of interest in things that are normally a source of pleasure and stimulation. Depression generally provokes a withdrawal from others and a turning against oneself. The person is left with conviction that they have not merely suffered some setback or important loss, but that they themselves are ‘losers’, and that nothing will ever be resolved in their life.

Depression is characterised by a particular set of changes in the way a person thinks, feels and behaves. As well as being an experience of psychological suffering it reduces a person’s sense of physical well-being and affects their sleep, appetite and level of energy.
