Unfortunately OP's attitude is common here at UCSD. A lot of undergraduates joke that the only reason they chose UCSD is because they didn't get accepted to Berkeley or UCLA. To be honest, it's the reason why I went to UCSD for my undergraduate degree; when I had zero idea which career path I wanted to pursue, name recognition (and inexpensive tuition) was everything to me. Initially, I felt bummed. I knew I was "good enough" for Berkeley and UCLA, but I found myself at UCSD, a college name that a lot of people treat as "almost prestigious".
It took a while for me to realize UCSD's own unique strengths: we don't have the same history and wealth as Ivy Leagues like Harvard and Yale; we don't have a captivating school spirit or fantastic football team like USC (which I believe has a big influence on overall student happiness); but the academic and research opportunities are ENDLESS! Almost every undergraduate who wanted to do research, found a professor willing to accept them. My classmates had an intellectual curiosity that drove them to study many subjects, whether or not it was related to their major. The majority of UCSD students have a thirst for learning/academia/research, and our school bends backwards and forwards to satiate our thirst, even if it means giving up Division I sports and a trendy campus town. UCSD is an unassuming school in that regard.
When I was deciding between graduate schools, it came down to UCSD and USC. I was very tempted to pick USC... the lack of school spirit at UCSD was depressing, and I wanted so badly to attend a school with a phenomenal alumni network, a famous football team, and pretty brick buildings with growing ivy. So many famous celebrities went to USC, too, like Steven Spielberg and George Lucas! Exciting!
But in the end, I knew USC wasn't going to be enough. USC wasn't going to give me the same research opportunities; they even discouraged doing a thesis. No doubt that USC was the right choice for many people, but with less academic research opportunities and twice the cost, UCSD was a superior choice. Only this time, I wasn't sad about my decision. Unlike my undergraduate days, I was confident in what I wanted to study, and confident that UCSD was going to provide that for me. I'm confident in myself, and therefore confident in my decision, and don't need the shower of compliments from the public to validate why I'm here.
OP, it's mind-boggling that you're at the #1 school for neuroscience, but can't find the pride in that. I agree with other posters here that perhaps you should take a step back from academia and figure out what's really going on. It's possible you might have some emotional issues that are being projected onto something unrelated. Or if stopping your academic program is out of the question, I suggest seeking a counselor - we have great counselors here.
