Letters to God

Years ago, when I was a teenager, my grandmother gave me a book filled with "Letters to God" about things teenage girls struggle with. I think it was called "A Girl's Letters to God" by Margaret or Margo someone, but it must be out of print because I cannot find anything remotely similar in a Google search. (It's not Judy Blume's book Are you There God? It's me Margaret)
However, the premise of the book (and the many new books of similar titles and even a website Letters to God) is that we can write letters to God. We may not get a physical letter back in the mail as a response, but the act of writing out our feelings, needs, wants, thanksgivings makes it concrete and sometimes you do get an answer. I have a friend who swears that God does answer her by things she gets in the mail. She'll be wondering and praying about something and will get a piece of mail that points her in the right direction.
Writing to God can be done as part of a journal or prayer diary or you can simply write out your letter like a real letter:

Dear God,
It's me... I've been wondering about...
I've been praying that...
Can you hear me, God?...
I need...
Can you help...
Why do I feel...
Thank you God for...
Have you ever written a letter to God? Did you get any response?  Whether you get a physical reply or not-know that you have handed over the prayer need to the One who really can take care of it.
