Well, this could all be a big prank by one of your friends. I suggest you talk to anyone you know that could have your instagram password first, but if it continues and you are scared you could talk to the school board, your parents, or even the police.
You should have sent the pic back stating that you grew up eating bloody knives and try to be a little more original next time.
Why would you post your question here Are you 6 years old??????????????
