How much trouble am i in at school?

[Chris]

So i know what i did was wrong. What happened was i gave my friend my other friends school code number. My friend went on it and made a status( not cursing or anything) and that was it. So i got called in and i told him i didnt make the status but i did give him the code. I said i was joking were friends. Now the princible said what i did is harassment and i told him im sorry and left.. I guess my friend was upset about the status. Which i feel bad. I was joking but i know it was wrong. They also have txt messages saying lets troll him. Cause i always did mess with him(Been friends for awhile) but he always made fun of me to as a joke also. How much trouble can i be in? I told him im friends with him. And he was upset about the status so he went to the office. Now how much trouble can i be in and what happens if i get charged with harassment. I feel really bad about this and idk what to do.
