Tearjerking but Beautiful Poem

I'm cleaning my desk, something I haven't done in months. I came across this poem, which was given to me at the hospital. I couldn't read it then but I can read it now and it's beautiful. I thought I would share. I don't know who wrote it but if anyone knows, I'd be happy to add it.

"Oh Mother, my mother
I touch your tears
invisible fingers
soothing your skin
I know you think of me so often
in the day, in the night,
in your dreams
going into an empty nursery
knowing I'll never be there
but I am...in your heart
in your soul, I shall always be
for you gave so unselfishly
of yourself.
Inside of you, you created
such a world for me
a world of laughter, of love
of sadness, of sorrow
every emotion people come to know
you shared with me.
And even though I may never
feel your arms around me
I felt your heart beating,
like a lullaby, singing me to sleep
and your spirit giving me a safe haven
already protecting me
nurturing me
preparing me of things to come.
But sometimes the journey
of life pulls souls apart
and yes, I had to go on
to another place.
I wish I could stay
I wish this was a decision
I could make
and I know you do too.
Know this wherever you are:
I will always remember
that yours was the first love
the first joy, the first soul
I will ever know
you gave me the courage to
go on in my journey
I hope you can do the same
for you
Your heart beat will always
call me to you.
Love, your child"
