Hi there! I am sorry you're going through that. I don't have any advice, I just want you to know I feel for you. Once when I was around 20 I got attacked by a group of teenage girls (they were my size). They wanted to steal my phone. Although they didn't get my phone, they did beat me up. I was scared of teenage girls for years after that. I don't come across these girl groups in secluded places anymore, but if I did I am pretty sure I would freak out and run for my life.
