We all sink in black holes
of bad luck,
Live again, live again
stamp out that pain,
Help yourself you cannot pass
the sadness buck,
Loss of this, loss of that,
loss of love that’s dear,
Melting sorrow from your heart,
Shout your joy of life, your joy,
and not draining fear,
Draw from inner strength
laid for a new start.
You must make those
living sparks again,
Be the person that you are
with awesome life
Be happy, smile wave to friends
and walk in the rain,
Then for sure
you will be yourself again
