The pain of Regret

I know I should be praising you for all the good You've done.
But lately I've let life's struggles steal away my song
No blue sky on the horizon as I sail these blackened seas
Sailing upon these cold black waters seems to be my destiny
The ghosts of doubts and regrets haunt the deck of my battered ship
Reminding me of all my faults and failures and the wages of my sin
