Last year my best friend missed her firm, Cambridge, and was just as heartbroken as you. In the end she went to study at her insurance, which she was unhappy about at first, but now she's made so many new friends, is active in countless societies, is crazy about her course and lecturers, she's pretty much forgotten that she ever missed her Cambridge offer.
I'm sure you'll meet passionate lecturers and students. Just because the university isn't as prestigious, it doesn't mean the people there aren't passionate about what they're doing.
