I've been doing terrible in school, like, not good at all.

Anyway my parents had a talk with my teachers and they all basically said I am too negative and too cynical. And then I realised, I am a cynical asshole. And I honestly have no clue what to do. I realise that I always make negative remarks, even to some teachers. I criticize people a lot on what they enjoy and what they do. A few of my friends are also very negative and cynical, maybe that influences me.

I really have no clue how to stop this since sometimes I can fake being positive and it makes people happier, but I just doesn't feel right to me.

I hope some of you can help me, thanks.
