i think im being bullied

okay so in my second period history class, theres this group of girls (T, L, and J are usually the ones who talk to me) and anytime i walk by their desk cluster thng, T starts giggling and goes "Hi (deadname)" im not out yet so its not my deadname that bothers me, its the fact i do not talk to T ever and shes kinda very popular. and then J will go 'hi pookie/best friend' and they all start chuckling. or they'll walk pass me and go 'hey (deadname)' and giggle. at first i thought thats kinda how they are, cuz T is so unfunny it hurts to the point her friends sometimes tell her to shut up but i looked more into it and that group only does it to me and N (my friend) no one else in that class but us 2, so i think im getting made fun of. another thing, my friend F and that girl L hang out sometimes. so Ill go up to them and L will just eye me up and down and straight uyp just tell me to go away cuz she doesnt like talking to me, whichh is fair, but im not talking to her? and sometimes when im near T and saying something, she'll go 'CLOCK IT' and giggle very obnoxiously with her friends, even tho shes never included in these conversations. so yeah i think i might be getting bullied or maybe this is just how she is
