Am i the bad apple for hitting a boy in my class?

I, 13 f, was sitting in my lunch period with some of my friends. We were showing each other our lunches, as we always did, to see if anyone wanted to trade. All of a sudden I’m surrounded by a group of guys from my class and they start reaching over me and pretty much dog pile on top of me trying to get a pack of my gummies. This made me extremely uncomfortable due to past trauma and I asked them to get off of me. Well one boy happened to sit in my seat with me and his friends reached over my chest to grab my lunch bag. His friend said, “DONT TOUCH HER!!! SHELL ACUSE YOU OF R@PE!!!” I was humiliated and I could feel my eyes starting to burn as a tear rolled down my cheek. The boy I liked was standing behind me when this was said and it made me very uncomfortable. I turned around and smacked the boy that said it and told him to never disrespect me like that again. Now all of his friends are calling me names and telling me I should just suck it up because “it doesn’t really hurt me because I just made the whole thing up”. Idk what to do Bc it was really traumatic and he’s down playing it as a lie. His friends keep saying I humiliated him. I thought I was justified but now I don’t know. Am i the bad apple?
