Fake friends (?)

I have a group of friends who I feel are excluding me or who may even be talking badly about me.

I met 2 girls who were new just like me, we became friends and formed a trio, during this period, there were two girls who were best friends and spoke badly of us, and one of them even bullied me. The problem is that one of the girls moved and the other one who spoke badly of us, became friends with my two new friends and became best friends with one of them, they are always together even at family events. 

Before, I had a problem with this, I felt jealous, but then I became friends with her too and got used to it, but the biggest problem is her behavior and how everyone seems to accept it. She screams a lot, and always wants to be the leader. Many would say that I can't judge her because I'm also an individualistic person, but I'm like that because I know that I don't work well in a group, she just wants to control everyone.

We do martial arts together and one time she accidentally elbowed me and BROKE my nose(I took care of that properly later), I cried on impulse but still left the mat telling everyone that everything was fine and that I could keep fighting, and she had the audacity to say that I was being dramatic. 🤨

They created a group chat without me, and last weekend the boy in our group came to tell me that she said "Ugh, Miyu is going, I won't be able to talk bad about her" and when I asked my friends if it was true, they said it was. Like? Hello? Neither of you see a problem with this? 😦

To escape the sadness that all this causes me, I tell myself that I prefer to be the best than to be loved by everyone (which this girl is), But sometimes being smart doesn't fill my void. 

Anyway, this has been a long rant and I really need advice.
