Perhaps a variation on Vigenere cipher? See
http://en.wikipedia.org/wiki/Vigenere_cipher
Take "help me he knows" as the key. The backwards R and the odd q (4th line, only "q" in text) both look a lot like numeral 9. Perhaps a clue to either key length or number of tables?
To my untrained eye, this looks more and more like a cipher, and one she wished to be decoded.
