as much as I want to help, you need to do this on your own, looking down and dwelling on those kind of thoughts will drive us crazy and maybe even insane. I know this firsthand. Grade 10 was a nightmare for me socially I was accused of doing wrong things, defamed and even threatened by others. Letting those thoughts flow freely will just eat us from the inside out and Oh boy, let me tell you, it's not pretty at the end (I suffered a extreme burnout). So please just enjoy the time you have left before school starts and don't waste it dwelling on the future, who knows, God has a plan for you. don't stress even it it seems impossible. nothing is impossible with God.
