Broken Pieces Of Shards

I don't know what I'm doing or where am I heading.. All my life seem to have break down and starts to fall apart.. Although I'm happy in appearance.. But how can I disguise what's in my eyes? This life is like a shard.. It grows as the life gets better.. And suddenly.. It breaks.. All there is.. all there was.. All completely broken and torn apart.. I can't run away from the fact that I'm sad.. Even putting a smile won't help.. Broken.. Anger and sadness has help themselves in my soul.. What should I do? How should I react? Is this fear that has haunt me since small? What is this fear in me?
