Just to throw this out there for another option. CRNA is also a good choice if you enjoy the critical care aspect of the medical profession from being a paramedic but want autonomy.
The schooling is intense, you'd have to take 2-3 years off from work to obtain it but that's better than the financial strain it may put on your family going to med school. They focus heavily on pharmacology and pathophys which many med schools do and will allow you to get the medical (anesthesia) education you want (if anesthesia is your thing), also some schools even merge med students and CRNA students during their first few semesters if you take a front-loaded program (didactic first).
The pay can be equivalent to a Family MD and you get the heirachy of being a CRNA! Also, you would be required to work in an ICU for a year or two prior, so that could afford you some time to save up and decrease the finiancial strain on your family even more.
Sometimes you can't have everything and be happy so sacrifcing your family for your career could come back to bite you once your done with your career, not to mention time away from family for pre-med, med-school, residency and specializing (yuck!). At least with CRNA family may have to pause for 26-36 months, which is a small sacrifice for a large reward, and in the end you'd still be able to balance family life and career goals! Just my 2 cents!
