If you are already halfway through med school and want to do psych or peds, for the love of god dont quit and go to nursing school. You only failed by a few points, you for sure can pass next time. There are lots of programs in all those cities and with an md you just need passing scores and a pulse and in 2 years you'll be an md living with your husband and a few short years from a 250k/year job. It sucks now but you're almost there. Find your second wind and power through.
