In class writing

My character is a person who sold a ticket to a girl who I know, and after that night she was committed suicide. I am a 20 years old college student who work for a place to sell tickets. I think I was send to a psychologist and I finally told this story happened to me. I want to wear in the waiter dress and hold a ticket in my hand all the time and I want to be looked so tired and weak. I want to site down on a chair and looking at the ticket to tell all this and finally look up at the end part. My goal is that I want to express the sadness  and hopeless of my mind problem. I haven't play to many silent character, so this time I want to use the power of the emotion in stand of the voice to express the passage.
