Fear as Depression/Sadness
Depression comes from a fear that things will never get any better. That fear fuels a hopelessness that reason cannot redirect. Allowing that fear to grow begins a downward spiral where the unrealistic fear builds upon itself. Eventually depression reaches a point that when things do improve, the emotion is so solidified that the good times are a lesser version of reality. This in-turn makes recovery even more difficult as the light looks dimmer as time goes forward. To curb depression we must attack that fear. The light of God can shine into the darkest depression. This comes from experience not a theory. It is unrealistic that things will always be hard. We cannot drift into hopelessness. This fear must be met with God and His reality!
