I'll weigh in on this because I was in a similar situation what feels like not so long ago. The difference is I studied social science. But, honestly, what's the difference? Once I graduated, I couldn't find a job that I liked or a job that paid me diddly squat.
I started at a community college and then transferred. So, granted, I probably did not accrue anywhere near the amount of debt that you did. But I was still unsatisfied and felt like my college education was a sham. It did not prepare me to live a life beyond school. Maybe that was my own fault, but I had to deal with it.
At the time when I was in my early 20s, I was consumed with that whole "expand your knowledge" and "don't worry about your career" and all that super liberal stuff. It seemed far away anyway.
Fast forward to that job I was working at after graduation. I think it paid $10.50. I worked there for a year and a half. Here I was, working along side ex-cons, high school grads, and I had a near 4.0 in college undergrad. Yet we all pretty much had the same skills.
I realized I had to train for a career that "not everyone could do." So I thought long and hard about that while I slaved away at this job I hated. I wanted to like my new career and I wanted it to pay me $100,000 starting salary.
There weren't many options available that could do that. Time was an issue as well. I wasn't looking to go back to school for any more than three years. Anyway, I found exactly what I wanted, and that's where I am now. But I couldn't have gotten to where I am now without those years of struggle as the impetus.
Figure out what you want first. It took me a while, but I found out I wanted a respectable career and money. I wouldn't waste your time in communications if you want similar things.
