Does my life suck?

So last night before I was going to bed at like 9:30pm because I have to work a double today starting at 6am and ending at 10pm, my roommate ask me "Not to bed rude or anything, do you sometimes think your life sucks?" The question kind of caught me off guard, but knowing my roommate I knew exactly what she meant and how she meant it. We then proceeded to have a lengthy discussion on how much I do work and how I help support myself, and blah blah blah. I tried to explain to her that although I work, I enjoy it and most of the time it is rewarding in some way. I also explained that I make all my decisions for myself and with life choices comes "consequences" so to speak. for example, I took an awesome two week trip to Australia this summer...it was amazing, but a little pricey and unlike many of my other peers at SMU daddy and mommy didn't help out. It still amazes me though after three years of living with her, she still thinks I must/should hate my life, working, and staying busy. I do agree I "overwork" sometimes, but who doesn't- well except her most of the time. Also, that's just me staying busy and happy, soing what I've always known and always done. And furthermore, I only do things I want to do, so no one is forcing me to work 16 hour days in the middle of the semester...Plus look what I'm doing at work....blogging and homework, so obviously it's not THAT bad. So when it comes down to it...I do have credit card debt, I do have loans to pay back after college, I work a full-time job while in school full-time, I pay for most of my own stuff, I work when my friends are out having fun...BUT I have had the same job for the past year and a half which a small percentage of college students can say, I have went on 4 international trips and 3 domestic trips in the last year and a half, I've meet some great friends at work, and above all I am HAPPY. My life doesn't suck and I wish she would understand that, or at least accept that I don't think that it does. But I mostly think that's a lost cause.
