Read this excerpt about Angel Island, an immigration station in the 1900s. The isolation and despair that everyone felt at Angel Island were expressed in the poetry that detainees carved into the walls of the buildings. The majority of these were written by the Chinese. Here is an example:

Nights are long and the pillow cold; who can pity my loneliness?
After experiencing such loneliness and sorrow,
Why not just return home and learn to plow the fields?
