My friends who turned on me

Before I start, i want to point some things out. Personally i dont think i have done anything wrong but again that is my opinion.

So when i was in grade 5, I was one of the most popular kids in school. But unlike other kids who are good at sports or their family is known for something or maybe they are down right famous, i was known for being nice. I would always give spare change to basically everyone in my school and buy them things if they wanted. I would give them food when they really wanted or needed it, i never made fun of people and even invited most people (even the ones I didn’t really like) to my birthday parties. Honestly, everyone followed me around. But after grade six hit, most of my best friends turned on me. Not that they suddenly started beating me up or anything. This was all mental abuse. They started calling me names. Ugly, Disgusting, they even started using homophobic slurs. They also would push me randomly, be mean while im minding my own business and calling me a monster just because I had asked them if they want to maybe do something after school. It wasnt too long until basically every single one of my friends turned on me and started doing the same thing they were doing. In the midst of this, i still had 5 or 6 friends who were truely my best friends. All of grade six was like this. Me going to school, getting bullied incredibly badly, me coming home thinking it was my fault and not doing anything to fix it. And i admit, that was completely my fault. Also I still gave them food and did what I had done in 5th grade. Basically I was being nice and they were being mean. Again, my fault for being nice when they were being mean. Anyways, when grade 7 had started, I thought it had been better because all the other jerks were in another class. But it just got worse. Then they started to talk behind my back. Saying everything they had said to my face but a lot worse. This kept on going for another 2 or 3 months until I was playing an online video game with some of my ACTUAL friends  who were nice to me up to that point. I was playing with me Best friend. Another one of my best friends. An annoying friend who was still nice at the time and my now best friend who was at his house. They decided to remove me from the party and play split screen with another controller I was begging them not to and everyone but my now best friend were responding with slurs and then they kicked me out. I instantly left the discord call and then saw them spam in the chat more slurs. I shut off my computer and started crying incredibly hard. Like i honestly felt like my eyes were flowing in a river (weird but whatever). When I returned they still made fun of me and yea thats basically how it went. Im now in 8th grade and im 14 years old but the bullying hasnt stopped and I still think it might be my fault.
