Sure there are times, even days where we all feel down - things haven't turned out the way we expected, missed out on that job or promotion, relationship problems - nothing seems to be going your way but when do those 'down days' become more serious? Depression is the persistent feeling of sadness or loss of interest in things you used to enjoy that lasts for more than just a few days - it's a lack of energy, poor concentration and feelings of guilt or worthlessness. It can impact your sleep and appetite, and for some thoughts of suicide can also be present. It can happen to anyone and in fact, 1 in 16 people in Australia are affected by depression every year. While we know there are a range of contributing factors that can lead to depression, it is important to remember that it is not a sign of weakness or failure - we are all unique and we all respond differently to different circumstances. There are a range of treatments for depression available including psychological and physical treatments, that are often used together.
