Dilemma

I never know where I shall go
Sometimes left, sometimes right
Sometimes I stand in between
With hands full or hands empty.

I never know how I shall live
Sometimes its hard, sometimes light
Sometimes it seems I am living dead
As its only breath, no thoughts at all.

Don't know whether to go up or down
But I roam in the middle;
Trying to find what life is
Giving something or keeping something.

I am worried dear friend -
What will happen after I go?
What will remain under this sky?
That will remind you about me each day.
