My name is T. Williams

I’m a Japanese loner

I used to keep things bottled up

A little piece of hell inside my head

Some days I wake up and I can’t trust anyone

The few friends I have aren’t close 

The speaker in this poem is T. Williams, a Japanese outcast with few friends. T. Williams audience seems to be a therapist, or a counselor of some sort, and he is quickly summarizing his ailment to this person. The message is that bullying is harmful. Making someone an outcast causes that person to not trust others, and causes personal anguish.
