Need advice on going back to my summer program or not

Ok so I doubt anyone will see this, but I really need some advice! So basically me and this one friend always joke around with each other in a mean type of way and we’ve been doing this since we met each other! But one day I was messing with her and this other girl who just started going to the program says “(my name) let’s be nice” but I’m messing with my friend and having fun so I don’t really pay her any mind, then later when everyone’s leaving I’m heading out to the bus my director is walking me out talking about how I shouldn’t bully anyone, and I’m confused but I don’t say anything cause I’m just trying to think of how I was bullying anyone? But next day I ask my friend if she was uncomfortable with me in any way and she said no and that she actually enjoys how we are together, so another day passes and I ask if the other girl has a problem with me? ( I didn’t mean it in a I wanna fight way just wanted to know) the other girl then starts acting like she’s better then me and I am not very confident in myself and I couldn’t get my side out cause I got scared so I go back to the lunch room, but I start crying so I go back to the bathroom with a friend, and im just crying so hard but since it was almost the end of the day I said I’m just gonna stay in there until we leave, but no a crew member comes and gets me cause apparently the director has something to say to everyone, so j go down to the theater and to sum what happened up she basically called me a bully infront of everyone and acted like I didn’t apologize to my friend already. I was so embarrassed I just left but I was crying so hard I had started hyperventilating and almost threw up, so instead of getting on the bus my mom came and got me, but my mom went and talked to the director cause she was pissed off, I didn’t want her to and said I just wouldn’t come back, the director wants me too and said it wasn’t her intention to embarrass me, but idk what to do. This is so long bruh
