I am lost

Before I start working at St.David Medical Center, I think I can speak a little bit English. But I am wrong when I get there.

First, I do not understand the way people speak. It is very different from what I have learn how to speak.

Second, people do not understand and do not hear me as I speak with a low voice as I am scare I will use the wrong words. All I do is, smile. I just give a sweet and big smile to my co-workers.

Last, I am lost in the middle of the people. Most of my co-workers are big and tall. One of my co-worker call me shortty as he is tall and big. His one arm is as big as my two arms come together.
