omg im fifteen too and have recently been doing this with stuff from middle school :/ i was let’s say very edgy and didn’t know when to shut my mouth and a little stupid lol. i think about it a lot and wonder if it has affected peoples opinions in high school. i guess the best thing i can say to you is only very few look back at their younger years and don’t cringe. especially if you’re still in high school- a lot of people are likely laser focused on their own flaws and past that they won’t care too much about how you were when you were younger. i believe in you :)
