Lyrics
the moon is gone and the night is still so dark I'm a little bit afraid of tomorrow

for this day was so long and hard for me and I've lost some of the things so far I have trusted

now I will close my heart and sleep a while bless my dream with gentle darkness until I could have my strength to wait for the light maybe tomorrow....

I've come through some betrayal, some old pains, some addiction to the love and some good-bye

like you did, like my mother, father did, I will cry a little while and wait for tomorrow

there's no way to be free from the loneliness it took so long for me to notice but now I am on my way to find my light maybe this day.... maybe tomorrow....

I will sleep a while, until the dawn wakes me up again I still believe....come what may....

there is no way to be free from love deeper we sink in the darkness brighter is shines in our hearts the lights of love

the moon is gone and the night is still so dark I'm a little bit afraid of tomorrow but I will go.... I'll go over.... I will go....
