Smile for me but dont die for me

What happened...?
To the good old friend i knew and loved.
The smile that made my day...
I do not know where it went.
Happiness is long gone in life,
However sadness is not.
Sadness, death,exhaustion and fright?
Is that all we have left in this somber place we call our life?
I dont understand why people choose sadness instead of happiness,
Death instead of life and a frown instead of a smile.
I miss that smile, that old exuberant style of living.
whatever happened to that place we call our home..."Earth"
