After visiting the dermatologist and have the vitiligo confirmed, look for another expert: psychologist/analyst.
The disease you affected too? Look for a psychiatrist, too.
Mental health professionals are still treated as taboo. Pure ignorance. They will help you accept, if you have not accepted, and, thus, to live well with the disease and be happy.
Acceptance is the key to success.
I spent about eight years in the analysis. Were fundamental to my process of maturing. I live perfectly well with the disease. Three months ago I went to a different professional, in search of anchoring everything I have achieved. I strongly recommend. Yes, it is possible to be happy, but the first step must come from you.
