HELP 10 POINTS WILL I GET SUSPENDED?

In school we had a substitute. At the end of cl, I took a broken pencil, and threw it at his head. He yelled at the cl and said he would bring the istant principal into this. Of course, I didn't tell him who I was and he wrote down our homeroom number. On monday I am going to be screwed. My friends dared me to and got pissed when we got in trouble. (the whole cl since he didn't know who did it) Will I get suspended? I can't or I will be dead. I get A's and B's but I have gotten in trouble before, but not like this. I was planning on lying and saying I was aiming for the trash barrel. I DON"T WANT TO GET SUSPENDED please help
