Invisible friend

How can I repay you
For all your help an care
When I was alone
You were always there
Many of those late, late nights
When you stayed and listened to me
I told you my deepest secrets
And cried enough tears to fill the sea
I asked for your help
And believed that you really could
When everything else failed
I knew you never would
When my day comes to leave
To the pearly gates and skies forever blue
There will be one thing I haven’t finished
That is until I say thank you
