I am sorry things are going badly for you.
But if you move to get away from ignorant people, you will be running all of your life. There are dumbasses in every country.
Think about the model Alek Wek. A lot of people find straight-from-the-motherland Africans to be exotic and beautiful. Embrace that dark smooth skin that ages slowly! Wear clothing and makeup that you like and that accentuate your unique beauty.
I think also that you are comparing yourself to other American blacks which there is no sense in doing. When you do that, you are comparing apples to applesauce. American born blacks have a lot of nonblack blood in them. The average American black is 20 percent white. There is no sense in comparing yourself to people who look like Aaliyah and Beyonce. Even though they are not fully biracial, they, and a lot of other American blacks have a load of nonblack blood in them. How else do you get people like Vanessa Williams? Stop comparing yourself to Americans and just be you. There is only one you.
