I agree with others though, use your creative side to come up with interesting things to eat. Myself, I have always been a breakfast fan so it is easier for me, but I think you are definitely on the right track with the journaling though- it will help you get a clear idea of what is really blocking you from beginning. Just knowing why you are having such a hard time beginning will help you to overcome the fear of going ahead with it.
Any ways what ever you decide to do make yr self #1 and take care of you!!!
