Story ideas? Severe case of writer's block!?

Well, what my English teacher would tell us to do when we have writer's block is to get a sheet of paper (it can be a scrap piece of paper or whatever you prefer) and a writing utensil and just write about anything that comes to mind without stopping until a certain amount a time pes by (for example, a minute). And if they're 15, they should be in a psychiatric ward of a juvenile prison considering that they are under age (they are not yet 18) and aren't eligible for a prison for people ages 18 and older yet. This may not be a good idea, but I'm going to try my best. What you could put in your story when they meet is that when the girl is with the guy, she doesn't hear the voices, which gives her a sense of normality, but at the same time hates it because she feels as if she's conforming to the people who 'hurt' her. (which is contradictory because she's the one who burnt a school,etc.) And the only reason she doesn't hear the voices is because she's distracted by the guy. The guy,however, feels even more depressed around her because he's reminded of the negativity of having a mental disorder and being considered 'mentally ill' in today's society. Therefore, they're okay with being with each other, but really hate it because they're reminded of a lot of negative things in their lives. I'm sorry if this plot line I gave you is egregious and such. I did my best and I hope I've helped you.
