Just need some help

I am 14M Now I wouldn't say this is bullying but a lot of my classmates and even my close friends tease me for some chest fat it inst a lot but they call it b*bs which just pisses me a lot and they also call me by a name "Moti gnd" Which is also horrible and I am done with it my close friends don't do it a lot but whenever they do it's very annoying I dont wanna lose them but I also hate the way they body shame me for being fat

Just wanted to ask if there are other people like me too and if there is a solution
