My college days are over but I can definitely relate to those fears Did you only apply to one place or do you also have a back-up place? It's good to keep your options open just in case. I would perhaps write down what your goals & wishes are for the near future and draft plan Bs, Cs etc. Things like alternative colleges to consider, work experience, gap year, travels, volunteering etc.
That way you can figure out alternatives in case you don't get into the program of your choice. good luck with the admission process.
