Became depressed after changing schools for a-levels

After changing schools, I've noticed a huge difference about how I feel about life, my confidence and anxiety when doing things. I changed schools as my school didn't offer the same high quality teaching for science as my previous school. I must admit some came from some bad stuff in my personal life. But a lot came from school. I've never been anywhere that has that much bullying and being popular by being horrible to others. Like calling someone a swear word or something racist is really 'funny'. My brother said I just got in a bad year. I don't know I just feel disheartened. Whenever I become friends with someone, others are like stop talking to the new kids. People are so unfriendly. (I also do 3 a levels so not much chance to mix as no one does clubs in college or anything. I'm hoping uni will be a good change? (I'm in y13 now thank god) Hopefully I'll start feeling happy again. I used to be pretty talkative and positive but have seen a huge shift.

Oh poor thing. I hope you will find a way to overcome your struggles and anxiety. Your life should not be weighted down by these things. Speak to your parents or adult you trust. It can lighten the burden you carry.
