I truly feel sorry for you, highschool was never a bliss to me, but nothing compared to what you're going through.
But try to not let these morons get to you, they are not worth it (that's what my mom always told me, and even if i know that it's not easily done, i still think that's the best advice she ever gave me).
Eventually you will leave highschool, and i swear that it gets better π
(i gather your french from your pseudo ? if you need to talk to a french buddy, you know with the foreign langage thing out of the way, or else, do not think twice and message me π )
