Dark heart

My heart is vacillating,
Vision is blurring,
Words are lost,
Smiles are shattered,
I am in great peril, darkness!
I see nothing,
My hand, lost its smoothness,
Mind, looking for peace,
Numbers, estimations,
Everywhere I went wrong,
and thereby hangs a tale,
reverting me to austere,
Oh lord!
whom can I put my trust?
