The rain (my tears?)

I sleep my days away,
they are so pale and grey
that I can not bear their sight.
And the stars
no longer shine to me
and I no longer remember the colour of the sky.
I see no leafs fall,
no flowers grow
nor hear the birds sing.
Only the rain (my tears?)
gets into my cold realm.
The sun and the moon
seen unknown to me.
And I wonder
is this the cause
of unrepaied love
or am I just dead?
