Ranting

So im in my 10th grade now and i got seperated to my classmates last year and i got into a section where they've been classmates since 7th grade, so im all alone in this year, well i have 3 other classmates that got seperated with me but they are all useless.
So our history/social/economy teacher gave a group project about environmental issues and so on. The leader on my group said that we should give a certain topic so i give my topic that is about destruction of coral reefs and water pollution ( i consult the leader privately before giving it to our gc and she approved), and the leader sent a vid that shows a the topic that have been choosen and my topic didnt get choosed and instead the illegal mining got chosen that is under of deforestation which is a also the topic that have been chosen (you can google it why illegal mining is under deforestation) and now it feels like i have no fucking contribution in the group. Even if i call out that its so fuckimg unfair, i will just get beaten up by them since they have a bond and im just an outsider to them.
