Depression is one of the most widespread afflictions of modern times and most people experience depression at some time in the course of their lives. However, some people experience persistent feeling of sadness, hopelessness, worthlessness and a sense that things are pointless and your life has no meaning. This is different from just having the occasional ‘blues’. Not everyone is a ‘glass half full’ person, but when you see things in shades of black, it is time to seek professional help to relieve the pain and emptiness that depression can bring.
