My junior and senior years of high school. My high school sweetheart was killed in a car accident the summer before our junior year. I moved the next summer after to get away from it all, and got hit by a big rig truck during my senior year.
5th, 6th, and 7th for me. 5th and 6th grade I had to transfer to these terrible schools but thankfully I always ended up returning to my actual school. I was also bullied by these two kids for a while.
Socially, 7th and 8th grade were the worst for me since I was bullied. 12th grade was the hardest academically since I was taking a lot of advanced classes to prepare for college.
