How to stop being treated like an *** by my friends?

Its honestly terrible. They try to make me feel powerless and it succeeds and it sucks, even my best friend sometimes does it. I understand how guys this age joke around, but i'm the only consistent target and i've had enough Im so pissed rn cause i dont want anyone to see that going on and every time i try to ignore them i just have to end up talking to them cause they basically make up all the dudes in our clas and i do have friends outside class, good ones, but i need good ppl w me in my class too and its rly actually dumb. Also I am terrible at roasting ppl so i dont even try cause I'm too nice for that. It honestly sucks i wanna kill myself, and also my twin sister is in my class and i get embarassed when these a**holes treat me like that in front of her. I just tell myself to put up with it till the end of the school yr but it just gets harder every single second. I'm so pissed off and i try not to be mean to anyone cause everyone knows im a nice person so i dont want to loose that reputation cause of those a**holes. I'm so pissed how can I get them to stop treating me like sh*t cause I'm not and I am better and higher then all of them and this isn't bragging, they KNOW IT but obviously do not want to admit it its so frickin dumb and I hate it so frickin much and I'm rly sad cause of it cause I had no friends up until 6th grade and I rly dont want to go back to that(8th grd rn) and so far it looks like i am.
