College Confusion

I recently got admission into a really good university and its even considered a public ivy but they were really strict about the the conditions of the admission (i.e. my exam grades) and I’m about to receive my grades in a weeks time and i know i didnt do well enough so I might have to go to a community college and then transfer to this university but I am so heartbroken and torn by this idk why

I feel like I had always set my eyes on the better university I never thought there would be a possibility I wouldnt be not go there ik its naïve. Im just incredibly stressed and cant sleep or even eat properly

I feel like I’ve let not only myself down but my family
