School is THE place to meet new people. In fact, enjoy the variety of people you meet at school now. It's harder to meet interesting people later on, after you are out of school. Most people are content with discussing what they saw on TV last night and what their lunch companion has on their plate. "Is that pesto?" Enjoy your school years :)
Statements like the above always frustrate me. I'm in school (and have been for a long time). Many people that I respect told me: grad school was the best part in their lives, that I should enjoy my time, and that it only goes downhill afterwards (no more research, family obligations, boring jobs, administration work, etc.). Great. But what if I don't like my situation right now? What if I don't like grad school that…
People stuck in a job they don't like because it pays enough to support there family have a reason to complain. You have no obligations but to yourself. If you think that you have obligations and try to use that as an excuse for why you are unhappy you are fooling yourself.
Find a different program, find a new hobby, meet a girl, start a company.
Being gloomy and getting angry that others are happy won't make you happy.
