Depression is an illness which attacks the whole body, including your physical body, mood and thoughts. It affects the way we eat and sleep, the way we feel about ourselves, and the way we think about things. Depression is definitely not just another blue day. It is not a sign of personal weakness or a condition that can be willed or wished away. The depressed cannot just merely pull themselves together and just get better. Without treatment, symptoms can last for weeks, months or even years. Today, we are living in a depressed society. And what is most scary is that we are also in an era where treatment is just another option many choose not to seek. Yes, depression is very serious indeed.
