Everybody seems to hate me at school, I want to change?

I'm in my last year of middle school, year ten and feel that everybody really dislikes me, all of a sudden at the start of term my so called friends stopped talking to me and are giving me dirty looks and talking about me when i can hear them. Everybody else in the year is in tight knit friendship groups and I'm practically invisible- a girl was handing text books out, she looked at my table where i was sitting with three other people and pulled out three books gave it to them and sat down, i had to go to the front of the class and get a book and got told off by the teacher, she told me that all the books were handed out and i shouldn't need two, she wouldn't even listen to my explanation. I've talked to my mum and she thinks they're just jealous as I am fluent in multiple languages when English is hard for some people but that's not really my fault. I just want to start anew the only problem is I am really shy. How do i make an impact? I wanna be known as a ***** that is not to be messed with! How can i do this? Are friends necessary, or acquaintances as i don't have those either, to be happy? I think need a change in attitude, any advice?
