If this COVID-19 crisis pans out the way it is expected to, repaying your student loans will be the last of your priorities.
With that said, many people with similar debt go into FM. In fact, I think with the exception of surgical subspecialties, the return on investment from pursuing something like interventional cardiology (8 years of training) is not that great when taking in consideration the opportunity loss.
Say you make 230k as a FM doc and can make an additional 100k from locuming at urgent cares. In the 5 extra years of training to become an interventional cardiologist, you would've produced 1.65M while instead of 300k (fellowship salaries). The 1.35M difference is enough to pay off your entire debt and even a mortgage.
Now one could argue that over a 30-year long career, the differential in pay between IC and FM is more than enough to offset the delayed gratification. However, I wouldn't really count on things staying the same for another 30 years.
Train fast and get out and starting making hay while sun still shines.
