Annoying brother is treated like a prince

I'm a 16-year-old girl (soon to be 17) and in my first year of A levels at sixth form. I live with my parents and younger brother, who's 11 and in his last year of primary school.

My issue is, my parents favour him and it's always been the case.

After I was born, they tried to have another baby quite quickly, but it wasn't easy and Mum had a few miscarriages. Eventually, five years after me, they had my brother. He was poorly when he was younger, so they've always treated him like a little prince.

I'm good at school and really good at sports too, I'm pretty much the model child, but I have to fight for any kind of attention or recognition.

My brother can sit in his bedroom for hours, playing online games with his friends, but never gets pulled up on it. There's no way my parents would have let me do that at 11.
