Everything Vox said and also listen to this song for cheer ups. Watch the clips too.

I don't believe that you have looked far enough into the matter.
For example, you could try different music. Or, look for something else that makes you happy. From my perspective is-- let me put this in a way you could understand... You come into a room looking for an object, but refuse to lift anything before you just leave.
You could, lift things and refuse to leave until you find the object....
......Make your hunger for life what drives your life.
