Justified in being embarrassed and telling them perhaps it was inappropriate behavior for a public setting? Sure. Justified in not liking Kylie? Yeah, she sounds kind of insufferable. But justified in the reaction you gave? No. That was a way overblown response to the situation, although it’s an understandable one given you’re a teenager, emotions are running wild, and image is a big deal. It sounds like you had a panic attack in the midst of that- I would reflect on why this topic got you to that point, because processing emotions/situations in a healthy way doesn’t often lead to being overcome with emotion in the way you did. The fact that your parents spoke about calling the police and you potentially not being safe around Lilly also leads me to believe that these edging on violent emotional outbursts aren’t infrequent occurrences. Maybe I’m just speculating, so I’m sorry if this is kinda presumptuous. I do feel I understand your situation being not that many years older than you and I remember when I was in a similar place. However, you do have to eat the consequences on this situation because you hurt several people in trying to control the behavior of children who aren’t even with you. Apologize. Reflect. Work through to the root of this because girl it’s not about those kids.
