In my freshman year, I pretty much lapsed into a state of not caring about anyone anymore and slacked off in my work by doing the bare minimum. The subjects that I was naturally good with remained with high marks though and I finally managed to pass Algebra I after trying for three years.
In my sophomore year, I took a break from algebra to take geometry, but found that I was terrible at it, so I slacked off even more. I started to get a little more socially comfortable again, but I think I was turning people away by trying too hard to be their friend. I also didn't go to anything that I was invited to because I didn't want to ask my parents to take me places. The one time I did muster the courage to ask them and I got to go, I had the best day of my high school days.
In junior year, my grades turned into a nightmare (compared to my previous A grades) as I was juggling homeschooling, public schooling, and school at a co-op. Midway through the junior year, I dropped a few classes to just settle with 1/2 credits for the first semester. From there, my grades went back up. I even passed Algebra II with a 98%. On the down side, all the friends that I left behind at the co-op (the classes that I dropped) stopped communicating with me and didn't try to invite me to things anymore.
Senior year was pretty much just a cruise through classes and finish everything leftover. I took harder classes and didn't do anything with anyone. I was just done with high school and wanted it over with. I pretty much got all good grades with the exception of my Computer Applications class which turned into hell. I have not had any confidence with computers ever since then.
