You start with a great hook:

How demeaning the feeling of being left out is.

The reader is with you from that moment on. You explain your difficulty in a way that is highly relatable. Not being able to speak your traditional dialect is, in a sense, more embarrassing than struggling with a foreign language. The language is part of your culture. The expectation is that you are familiar with it. You are 'left out' because people are surprised by your lack of fluency.

Your language usage in this piece use a little work, but you write effectively. You are honest and direct, and therefore gain the empathy of the reader.
