Why use someone else's words, moonlightsonata? Many religions such as Christianity have pre-written prayers, and encourage that kind of "prescribed thinking," and you could find that in some paganism paths, as well. But it's my general understanding of paganism that it encourages one to develop a certain intuitiveness, an inner voice, from which we freely express our being.
From this point of view then, I'd encourage you to try writing from your heart. Meditate for a while to get in touch with that part of yourself, then be clear about what you want and why. Speak from the center of your being.
Ironically, it seems here that it will take a bit of (upfront) courage on your part for you to write your own prayer ...for courage.
