Will eating better/whole food help my Vitiligo?

Boy this is really hard, even harder now that I have to write about it lol. I am finding that it is hard to not eat processed food. Why is it so easy and inexpensive? Eating healthy takes more money, more time, more preparing. I can not wait until this becomes a lifestyle and so easy I dont have to think about it. I feel the momentum coming mostly because of the recent diagnoses of Vitiligo. As of today I have 36 patches on my left hand and 20 on my left. I have 1 patch on my toe and armpit and a few little dots on my foot.It is really stressing me out. The thought of it going to my face is so scary to me. I have been reading alot about it. The doctor makes it seem like its no big deal and there is no cure. I find it hard to believe that there is no cure. Maybe it is true but I want to find answers. I asked her if my immune system is ok. She replied "your immune system is just as strong as the next person" I told her I am not so much afraid of the discoloration in my skin as I am of the fact that my immune system is attacking itself. I have always been the type of person that does not believe in covering the symptoms, but actually finding the reason why our bodies are doing this. I believe our bodies give us signs everyday when something is wrong. Some of us chose to listen and others chose to cover it up and make it go away.
I feel that in all of the reading I have been doing, it has one thing in common, eating a vegetarian diet with whole foods has been the best option. I have been wanting to be a vegetarian for a few years now but I am definitely finding it hard to do. Also there has been some mention of avoiding alchol because it will interfere with your immune system. So giving up meat, alchol, and processed food and trying to exercise more. OH boy do I have my work cut out for me. Anyone who knows me well will agree! But at this point in my life, I do believe it is time to make changes that are going to prolong and better my life. If it isn't' going to benefit me health wise then I don't want it. Well that sure was easy to say lol. We will see when I out and want to drink.
I know what I want. I know the lifestyle I want to life. I know that I want to set a good example for my children. But doing it is another. My kids are actually inspiring me to be healthy and exercise. I am so lucky :)
Tomorrow my plan is to wake up at 6am (or 7ish) and go jogging with Dee or Nasser or both! then get back on track with juicing. Wish me luck. Thanks for reading and sorry for any grammar issues. I am not the best writer, I just want to write from the heart! :)
