It is also inspiring to read memoirs of other people who have overcome depression and other mental illnesses. I will include a list of some good memoirs and books in my next article. Realize that depression is not your fault. Obviously you did not ask for the big dark cloud to descend over you - it just happened because of some mixture of biochemical and situational factors. The most important thing is that you realize that it is time for you to take your life back.
Depression is very treatable through medication, therapy, and a new and enhanced attitude.
It also helps to think of depression as a demon that you can fight and win. Depression is a foreign substance that has entered your brain and threatened your tranquility. Depression is not who you are, it is just an invader that twists the words of your soul. Once you fight back, you can regain the substance of your mind with a more realistic and positive perspective. Don't let the overwhelming feelings distort your true personality.
