There is only endless sorrow , even if any other happiness not exist in my world.
In my world, there seem to be no joys but endless sorrows and depressions.
it seems that all my world is filled with endless sadness and sorrowness.
There seems to have no happiness but endless sorrow and sullenness in my world.
In my world , as if happiness didn't exists , there are only endless sorrow and melancholy.
