White Skin - Vitiligo. Doctor again?

I went to Skin doctor who got good ratings in Practo for Acne and Scar problem. He suggested few medicine and ointment. After using that I got severe itches in my leg then it turned into white skin. After few days I got in my back. I went to doctor again he is shouting at me why I didn't come for Acne and Scar treatment after one month. I told that I am afraid of this white Skin so that I didn't come. He just saw casually and said we can start treatment for That also.  He didn't even tell what is that. He gave elidel melagin and other medicine for acne and scar which came around 3000rs. Still I am having white skin and it is not getting cured. I am really afraid. I started studying about this and everyone Telling this is vitiligo and it is not curable. Can any one Suggest me best I am afraid to go that doctor again
