feel so dumb

my friends at school where talking about their university offers today one of them got into cambridge for economics and the other got into oxford for chemistry i feel like such an idiot around these people im just someone who stuggles with the majority of subjects and can only do particularly well in maths or computer science i feel like they don't even like me and are just trying to be polite i just hate how they are the same age as me and have been able to accomplish so much
