You posted on here asking for advice and then did the very thing you were advised not to do.
She got scared and walked away from you. It sounds like you made your point very clear.
The only person you caused harm to in this situation was yourself. You ignored the advice you were given and as a result, you almost assaulted the girl and now you're suspended. Do you want to be a bully? Because your actions show that you're fine with it. It is better to be loved than to be feared, trust me.
Attempting to cause harm to someone else causes harm to you as well. Cuts and bruises heal, but you will have to live with what you tried to do or will try to do. I experienced the same kind of thing when I was your age. She talked shit about you. Okay, now move on. Teenagers talk shit. It's extremely common. If someone says something to or about you that upsets you, then that means you value their opinion. The only person you are fooling is yourself.
