It gets better
I was bullied terribly from 7th-10th grade, and then isolated myself from 8th-12th grade. Isolation was a survival instinct. I graduated with no friends, and no one even knew me. I went on to college. It took a while for me to come out of my isolation there (as I was fearful) but after about 6 months I was able to. I left college with dozens of friends, and a girlfriend. A year after graduation we married, and a year after that we had our first kid. I now have 4 kids, and many friends.
High School memories are still hard for me and still affect me deeply, but my life is better than I ever would have imagined.
When you are bullied in high school you feel like nothing will change. You also feel like it is somehow your fault. After high school things change substantially and you realize it was not anything to do with you. It gets so much better.
