What is happiness?

I was in COMM395 (Deliberative Tradition and Democracy) tonight and we decided to hold a "Socrates Cafe"..Dr. Phillips wrote a book entitled "Socrates Cafe" that illustrates exactly what one of these consists of. Basically, it is an opportunity for people to gather and talk about things with no sense of authority/hierarchy present. We were asked to bring in a philosophical question and everybody voted on which one we wanted to talk about. We settled on "What constitutes a happy life?" Needless to say, there were some pretty diverse answers and I really took the opportunity to self-reflect. Although there is not one true, objective happiness, there are some similar traits that made people happy in class. It really allowed me to realize that I'm working my ass off and I'm wasting an opportunity in my senior year to enjoy myself and socialize with people I may not see very often after graduation. Taking 18 credit hours, working an internship, working at the gym, cheerleading, and balancing a social life is extremely difficult. The one with the least amount of mandatory responsibilities is my social life so I usually elect to defer it to another time. Unfortunately, it happens over and over and over again and I'm so tired of it. I feel like I need to take more opportunities to relax and hang out with friends and stop being so uptight about school and work. It's doing NOTHING besides stressing me out and I don't like feeling like this all the time. It's gotten to the point where all I think about is what I should be doing as opposed to what I am doing when I'm trying to have a good time. The combined definition--among the other students--seemed to reflect a "well-balanced life" or "a valuing of important people in your life." It made me think about how much all of my day-to-day friends, professors, acquaintances, and others mean to me and I'm slighting everybody because I worry too much about the bullshit that stresses me out. Therefore, I'm asking all of you to keep me in check. These habits won't be easy to break so I would LOVE for you to make me relax, make me hang out with people, even if I say I have something due in three days and I need to work on it. I have to think about the mayonnaise jar and coffee story (if you haven't seen it, definitely google it!). There's always time for a cup of coffee with a friend.
