Congrats!!!
A word of warning about med school, or any intense graduate program. It can be hell on the family. I have quite a few friends, male and female, who's marriages have suffered greatly (some ending) from the stress of medical School. It doesn't let up until about the 7th year when you finish your residency and finally get established. Sounds like you would do EM, which is one of the toughest of all specialties for time and stress.
God Bless!
Good Luck though! If you want it you can make it happen, and if your family is committed with you, it can even be a great experience.
