Are my friends toxic ??

Hello , so I'm a high schooler (16 y.o) , I used to hang out with my two friends since middleschool but the year we passed to HS , the changed somehow .
They would tell me jokes that hurt me like :
why you dress like this ? -You look ugly - Mmmh , You're not pretty - You should try something else - Your outfit is just laame
And there is that day , I felt like they insulted my MOTHER . I am the youngest among my siblings so my mother is her 50's . while those two girls are the oldest , their mothers are in the 30's . So , when we met one of their mothers , I said : wow , your mother looks young !
the other one replied :WeLl oUr moThErS aRe YouNg (〜￣△￣)〜
Btw , they met my mother before , and then I felt rrly rrly annoyed , like she said it in a manner , like she wante to hurt me saying that.
I don't talk with them anymore , I want to finish this "friendship" but I don't want to be lonely and the same time I wanna live my high school days with good memories (≧∀≦) Please tell me what should I do ? and thank you so much for reading (●'◡'●)ﾉ
