This simple song has helped to cure many of my depressions.

I can see clearly now, the rain is gone,
I can see all obstacles in my way
Gone are the dark clouds that had me blind
It’s gonna be a bright (bright), bright (bright)
Sun-Shiny day.

I think I can make it now, the pain is gone
All of the bad feelings have disappeared
Here is the rainbow I’ve been prayin for
It’s gonna be a bright (bright), bright (bright)
Sun-Shiny day.

Look all around, there’s nothin but blue skies
Look straight ahead, nothin but blue skies

I can see clearly now, the rain is gone,
I can see all obstacles in my way
Gone are the dark clouds that had me blind
It’s gonna be a bright (bright), bright (bright)
Sun-Shiny day.

Johnny Nash - I Can See Clearly Now
