This is something what I've experienced a little. I've always had quite good marks, so I've always been kinda "the nerd" and this "uncool girl". It wasn't bad though. A long time, I even was friends with the cool kids, but then I decided to look for new friends...
Anyways, when we all got into 11th grade (this grade prepares you for the next to years. The finals are equivalent to the high-school diploma you get in the US, but they are kinda optional, as you can finish school after 10th grade or you can make those "second finals" after 13 years of school. It's complicated),
they put us into an entirely new class. I had just a couple of the old people and the rest was completely new to me. It all started really nice and I got along with them really well. But, guess what, when I got my first good marks, they started to talk about me behind my back badly and so on. They would even throw comments and laugh in class when I was talking. But they couldn't ignore the fact, that what I was saying, was right. So they just keep acting jealous.
I just want you to know, that those people are jealous, unsatisfied and mad. Or just too cool for the world. You shouldn't listen to all of them. Just move on and don't even react to them. People always talk, no matter what you do and you could never ever comfort them all, so comfort yourself and live your dreams. You will feel proud and happy about your own person in the long run. Seek for help, if it gets too bad, please. Even though I have to deal with bad critics a lot, I've never experienced bad bullying, BUT I know it's the worst and if you feel under pressure, there's nothing wrong with getting help (professional or not, it's up on you) and it's not weak.
Basically, this is what I wanted to say. I do feel like it refers to the topic of my little blog, it is relevant to all of us though.
