I have had a similar experience just like you, Joua, being in a strange and different country. I was young as well, and it was difficult for me to adapt to the differences and learn a whole new language that I have never spoken before.
Looking back, I remember that I had trouble communicating with others, so it was tough for me to talk and make new friends. I felt really lonely and out of place.
Through all of the bumps in the road, coming to America has enabled me to learn a new culture and has given me the confidence to overcome my fears and make the best out of it. Reading your story opened up many old memories. I came to realize that while we are all different, coming to a new environment has a life changing effect for all of us.
