The amount of people suffering from chronic stress and depression is on the rise. In fact we probably all experience both to varying degrees at times. Tony Robbins suggests that in many cases overwhelm precedes depression, so it seems like a great topic for me to focus on; plus I have worked with a number of people in this space.
Some background
Firstly, I am assuming all of us have been overwhelmed before. Whether for short periods or longer periods. The short stuff is manageable. It is the longer, chronic overwhelm we want to avoid.
