The speak below is a girl who has a leukemia. She can't go to school and is now picturing a scene at her class. I don't understand what the last sentence means exactly. Please help! Thank you.
I am supposed to start sixth grade in a few weeks. I can see it now.
My class all sitting at their desks except for one empty desk with a laptop sittion on top of it. I'm in bed with my webcam, staring pathetically out of the screen at them. My friend walks by without noticing. I have been reduced to a picture on the screen.
'I am now nothing more than a picture on the screen'. Her leukemia treatment means that she can't be a presence at school: she's just an image on the screen of a laptop.
