I want to kill the kids in my school?!

you ABSOLUTELY SHOULD NOT kill anybody!
i used to be just like you, everybody made fun of me, i didn't have any friends, school was torture everyday. but life goes on, those immature kids may take alot of time to "grow up", but please don't kill them, you will only ruin your own life, and your life is worth soo much more than that!
also, those kids have parents and i'm a young parent of a 5 year old, (i know its not necessarily the same thing) but i would literally do anything for my child. i also would go crazy on anyone that hurt my child.
if its really that bad, ask your parent or guardian to be homeschooled. homeschooling is what i did, eventually. and it helped alot. although you get rid of your high school experiences that way. but maybe for you thats a good trade.
please please, think about what you're saying, you are so ready to end anothers life. life is precious and you will be giving yours up!

You should not do anything stupid. - Remember the phrase... Dont get mad ---- Get even.

In your case I would share your feelings for your family first of all. - Then you will all together make up a strategy of how to act.

well...killing isnt good. you shouldnt do it. ask your oarents if they will take you to a diffrent schoool or be homeschooled u will go to jail if you do that. or talk to your school counsler

Don't kill them, embarrass them. Ignore them and scare them.... Come to school looking half dead and give serious creepy exosist like stares and just make them pay.... :)
