I'm not sure why the government would want to kill you...do you know something you shouldn't?

Since you are in middle school I'm guessing you are under 16 legally you have to attend school...if you don't you, your parents etc will get into trouble possibly even involving the police....it's really not an option....

Focus on where you want to go and who you want to be when you grow up and just lay low for a while until you get there. I hated jr high but worked really hard so I could succeed later on...it worked out pretty well...and really without a high school diploma and these days college it's hard to get a job....
