Finish your residency. I'll tell you why.
First, your MD/DO is basically useless without a residency. You already know this. No one here is going to tell you about some magical "suitable job" that will let you pay off your loans while paying you a good salary, because there isn't one. Considering how hard you've worked to get this far, you deserve better than to basically spend the next few decades working at a white collar middle class job that is going to leave you living paycheck to paycheck because you have six figure loans to pay back.
Second, residency sucks. People can romanticize it all they want, but it just sucks. The good news is that many of the worst things about residency, namely that you have little or no control over your schedule/location/work life balance, all can be fixed to a point of tolerability once you're an attending. Don't like your location? You can pick up and move. Hate seeing patients? Want to work fewer hours? You can quit that job and find another one if they won't let you work fewer hours, or work locums, or go into academia and teach/do research, or go into administration, or do a fellowship, or any of a large number of other options that suddenly become open to you once you have that piece of paper.
Don't get me wrong. I didn't like hearing people telling me the same things I'm telling you right now any more than you're going to like hearing them from me. But the thing is, they were right to tell me to stick it out. I'm in a position now where I can plan my way out of clinical medicine, and it's going to be a much more comfortable future with a board certification than it would have been without one. Two years from now, you will be in a much better financial and career position as well if you stick it out.
