The same that I mentioned in the previous question: look for a psychologist. If you are very much upset, also look for a psychiatrist.
From now on, my friend, you will go through a lot, and does not need to be alone.
Look for contact with other people who suffer from the same disease, the exchange of experiences will help you.
Dedicate yourself to the treatment but don't frustrate yourself if it doesn't work. Many things in life require dedication, but the result does not depend on us. So with the vitiligo.
Be strong. ;)
