He hasn't gone mad...he's depressed and is looking for change. They continue to look for change so that they will feel better. Once they find something different, the euphoria of that particular change will be short lived because they discover it's not working any longer and then they go seeking for change again.
To us, they appear to be mad, but they truly aren't. They aren't thinking rationally because of the emotions that are running wild. They think that they are just fine, while we see the irrational behavior and shake our heads...but this "madness" will settle down in due time...but it has to run its course.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
