"Another leaf has fallen"

@Uootem

When I first realized that you were leaving
I didn't expect to do much grieving
  for I was of the mind to be believing
  that someone else could soon take your place.

I thought you were just another autumn leaf
that would inevitably fall from my tree
  to join the others in a pile below
  and to be swept away swiftly
    by the next wind surely to come by.

But somewhere in my heart
i soon realized that the leaf
  i once thought you were
  was actually a whole lot more.

You were that leaf that made the tree full,
that gathered the sunlight of each new day
  and gave the tree something to live for.
  You made sweet music when spring breezes blew,
    provided the protection from the harsh summer sun,
    and added the color to a gray-filled fall day.

Now my tree, with bare branches exposed
is susceptible to the unwanted winter cold
  that is filled with so many empty emotions.
  the sap that once ran through my branches
    giving life to my living has dried and gone.

It seems that you once worked a miracle and
turned the spot where my tree stands
  into the warmest place on earth.
