I hope it'll be worth it financially, but I'm pretty sure it'll be worth it emotionally. If you want to go into medicine, you take any spot you get and take out the loans to finance your education. Balls out all the way.
I'm fortunate in that I don't have any undergrad debt (my parents were generous), but I'm on my own for grad school. That said, I'm in for 100k currently with 3 years to go and will probably owe about 375-400k at the time of graduation. Most of it is at 8.5% and some of it is at 6.8%.
Cripes man
Average debt at most schools hovers around $160,000 per graduate IIRC.
I shant complain about my loans any more.
