I'm sorry you had such a terrible high school experience. I can relate in some ways.
My brother and I were home schooled by our mother since kindergarten, but at age 13 (11 for my brother) she abandoned us which resulted in divorce and the inability for either of us to continue home school.
We were put into public school in the middle of the year, which resulted in bullying on both of our ends, just for being the new kids.
Despite what a lot of people might think about homeschoolers, my brother and I were very social and had many friends who were also home schoolers.
We were not able to hang out with them anymore and these new kids at public school were vicious, so we were mostly on our own.

Throughout high school I received minor bullying, but primarily isolation. Some kids were alright, but most would leave me out of everything and I was even told to **** off at lunch one year, so I gave up and stopped eating lunch altogether.
I'd hide in the library till class started again.
I'd get so envious hearing what amazing things everyone in my classes had to look forward to with each other, while I was left out.
I came to realize that these people were simply not worth my time whatsoever. They were shallow, stuck up, and just plain ignorant.

I'm really sorry to hear that you were treated so badly by similar people. I have never tried to contact any of them again, because I know for a fact that most of these people will never change.
