Readers dilemma; Struggling to fit

I am in Form Four in a Nairobi school. I grew up in a remote village and before I joined my current school, I had never been to the city. My parents are teachers and our home is considered well-to-do in the village. However, I found myself completely out of place when I got to Nairobi and since Form One, I have been struggling to fit in. I am confident and admired at home, but very timid in school. This has affected my self-esteem and performance. What do I do to overcome this?
