I encountered and have continued to encounter racism in Spain.  The way the locals treat black people here is awful and very different from the United States.
In the first week I was eager to learn about the city.  I felt like everything was new and I behaved carefully in my new host home.
Now I am comfortable in the city.  I can be myself in my host home.  I still don't feel as at home as I do in the US, but I have adjusted to the way of living.
Time!  This was the only way to adjust.
I value myself and my individuality now more than the habits of my friends.  Here, I have new friends but no one knows me the way that friends at home do.  I feel like my way of life has slowed down and I am no longer rushed all the time.
I think I know myself better now and in the future I will be able to decipher my feelings better in every kind of situation, not just related to cultural issues.
