Sometimes a negative feeling wins

Sometimes a negative feeling wins the fight against me
then I feel like a piece of wood that floats alone in the sea
floating further and further away
no reason to stay
a big black cloud over me
the flashes of light I can see
then it really starts to thunder
and then I feel myself go under
so that I no longer have to wonder
what the future will be
if there is someone out there who really loves me
