I have no friends and I am afraid to go back to school?

In grade 3 I was really silly and I was a bad student and I was always the one who was cracking up jokes and giving the teacher a hard time, the school was about to suspend me and my dad got into a huge fight with the school board and ended up switching me from a catholic school to a public school. I went to a public school for 3 years but then this girl who was my friend started to be racist and ped negative comments about my dad and us being catholic. I told him what she had said and he once again removed me from the public school I was at and put me back into the same catholic school. I told him not to and begged him, but he did'nt listen. Anyways, In grade 7 ( last school year ) no one liked me because of stuff I said to them in grade 3.. they all made fun of me and all cornered me and called me names and hurt me.. I ended up making friends with these 3 girls and they helped me change my style so I look prettier so people would stop insulting me on that. And I did and the bullying kept going on. The 3 girls ditched me in March and said that all the teachers are starting to hate them too because of the stuff I did in grade 3. I got into a huge fight with them and ended up not speaking to them for the rest of the year. So at this point all the teachers and students hate me - every single one, even the ones that dont know me but threw there friends. I ended up spending every single recess alone.. sitting down doing nothing. Every group project i did alone while everyone else had a partner. I'm scared of going back on the first day, please help what if I dont make any friends im 13 btw
