What should i do about this (school prob)?

hey what should i do about this . i cant rely on my parent for advice cuz they would just say take it to thee office but thats not a good i dea cuz i would get called a snitch. okay so this kid at school started getting alll in my face (but waz supposedly playing) so i put my arm up in self defense and then acendently hit him hard in the jaw. then he hit me in the back of the head (i didn't feel much though ) and then the teacher started to get in cuz we looked like we were about to fight th( well he was i was just defending myself cuz i didnt want to start problems cuz i know that would affect me in thee future) then he ended up tryna hit meh and acting weird like the looked like he was going to hit me but put his hands in a flinching liike motion i kept on blocking it and then he was like im not touching you looking back ive should ve ssaid stop but i cant go back and he also got this vase and pour some water like on my lower back i started getting reall mad so i ended up going outside with my friend to cool off cuz i was getting really fustrated now to the point i was punching the lockers and a few tears coming out the teacher tried talking to figure whats going on and then i was like holding back tears violently but the guy said i was faking cuz he saw me smile (which was actually me holding back tears and faking a smile to not worry any of my friends ) and then the teacher called an adminastrater (though i didnt want to take it any further) and then i dont knnow what was going on inside the cl . but now all i know is that this one girl wants to fight me. i have my guy friends to help me but still the kid waz a black kid (not tryna be racist) that acted ghetto and so waz the girl (but she was mexican) what should i do . i dont really wan to fight but i kinda dont want to back down cause that will just say im weak and get me teased at school the last thing is i want to thank you in advance for reading all this and for your advice. i also told this to my older brother who worked in juvie hall for a while but that waz on facebook and he hasnt replied
