I think that though you do need to work on the grammar and punctuation and sentencing, there is a great idea implanted in your writing. I suggest making this the prompt for a new story.
You could start out with the boy not thinking that the story was true, and entering the abandoned bathroom. This way the reader is still creeped out and worried for the main character.
You could also use an age for the boy (both of them), and tell why the boy in the mirror is first off in the mirror and second whh he skipped his classes.
Great work, can't wait to hear more!
