I don't know if it's a cold, flu, or just blue, but this old song has been on my mind ~ I just love the lyrics:

I see the moon
And the moon sees me
And the moon sees the one that I long to see
So God bless the moon
And God bless me
And God bless the one that I long to see
It seems to me that God above
Created you for me to love
I once had a heart called mine you see
But now it has gone from me to you
So take good care as I have done
For you have two and I have none
I see the moon
And the moon sees me
And the moon sees the one that I long to see
So God bless the moon
And God bless me
And God bless the one that I long to see
