Raw Food to heal me

So I have been on this raw food path for about a year and a half. I really got into it summer 2005 due to Depression that I have had since I was fifteen years old. I am now 25. I believe that my Depression has been due to my mother dying when I was fifteen as well as accutane (drug proven to cause Depression in many) as well as some anti depressants that I took. The longest I have ever gone eating strictly raw food was for two weeks at the Anne Wigmore Institute. I feel they have a good program but I left there broken hearted as I was hoping that I would leave with my depression cured. I also went to hippocrates for one week and left there disappointed when my depression was still a persistant problem. For the past year I have eaten at least 75 % raw food overall and for the most part have juiced consistantly around six days a week, fresh vegetable green juice. The only real difference I have noticed is that my hair is healthier and I have lost weight (about ten pounds) and I feel much prettier. However, I don't have the results I want. I am attempting to go 100 % raw now for a couple of months because I really want to heal myself but it is so easy for me to get discouraged thinking it may not work. Also, I usually can go about a week on raw foods and then the desire for something cooked is overwhelmingly strong. Anyways, I really need some words of encouragement and tips. Do you think going 100 % raw will truly heal me? Or at least make a big difference? How long did it take for you to really notice a change or any benefits?

Thanks,

Dawn
