Taking the following steps will help you develop coping strategies according to your particular case and needs:

Find a doctor who is knowledgeable and experienced regarding Vitiligo. Your doctor should be able to listen to your concerns and take Vitiligo seriously. A doctor who states: "there is not treatment for Vitiligo" or "it is only cosmetic" is probably not the right choice.

Learn as much as possible about Vitiligo in order to make well-informed decisions.

When necessary, a psychologist or therapist who has experience in counseling people with medical conditions which affect their body image should be able to work with you to strengthen your self-esteem and your sense of personal dignity. 

If in doubt, always seek professional advice regarding stress, anxiety or depression. Stress can frequently be prevented or controlled through a number of actions adjusted according to the needs of the individual. Anxiety and depression are treatable. Usually the best way to treat these conditions is through regular sessions with a therapist and, when necessary, medication.

Consider exchanging information and support with other people who have Vitiligo.
