Can't Sleep

I can't sleep tonight,
it's so dark outside clouds cover the moonlight,
hopefully time will let me my sleep find,
until then those warm tears will mark my pillow and sorrow my mind,
it's like I'm stuck on a mountain I can no longer climb,
it's like no matter how hard, it is useless to try,
but darkness is around I surely can not hide.
I wish this is why, blind people don't cry,
there is nothing to miss - not even the slightest sign of light.
But I'm tired now - I'll close my eyes,
and whisper myself...goodnight.
