Career Advice For College Graduate?

Hi, I'm a 24-year-old recent Comp Sci: Game Design graduate. I'm lost when it comes to my career. I haven't had any luck applying to jobs in game design / world design. An unfortunate event happened that unfairly delayed my expected graduation time by a year and a half.
My early twenties have flown by so quickly, and the only real work experience I have is 7 months of corporate retail crap. I'm going to start working 30 hrs. / week as a Calculus tutor, but I'll only be making $18/hr. I just want a job or internship that looks good on my resume. Sometimes I wish I could've gone a different route.
I'd say my creative portfolio is pretty good, but I'm still not satisfied with it. I could continue making creative works, but there's a good chance that I'll still be broke and insecure. Whenever I want to pursue a different career path, I fear that all of those years of hard work will go to waste, and I might end up even more insecure and guilty.
Maybe this is a bit irrelevant, but it doesn't help that many of the girls I've met have dumped me over my situation. I'm about to go on a date with a pretty smart girl with similar interests. Should I just call it off? I'm afraid that she'll ditch me as soon as she finds out about my situation. But I'm sick of blowing opportunities due to insecurity.
If you have any career advice, please let me know. I would like to find internship / day job opportunities that could advance my "career".
