Generally, I am supportive of nontrads (being one myself).
BUT . . .
You are 49. Realistically, if you started today, it would be at least 3 years before you even started med school (at 52 years old). Finish med school at 56. Finish residency at 59+, depending on specialty. I would NOT want to do any residency in my late 50s. Meanwhile spending tons of money and likely going way into debt. Then . . . what? How long do you think you'll realistically want to be practicing?
Sorry, maybe others will be more supportive, but I think I have to rain on this particular parade . . .
Especially given the "DVM or MD" statement. If you don't even have that one figured out, you're not even at the starting line . . .
I don't think you need therapy, but definitely some realistic career counseling.
Don't let age be an issue. I was 48 when I started my prereqs (only 2 per semester, since I work full-time). When I apply this summer I'll be 52.
I look at it this way: If I start med school in 2009, I'll be 56 when I graduate, 60 when I finish residency. Regardless what I do, I'm going to be 60 anyway. Why not be doing something I love and am passionate about?
Some argue that I won't have very many years of practice before I retire and I'll have a huge debt hanging over my head. If I don't go to medical school, I'll continue on the same path I've been on for the past 25+ years (bookkeeping) which is utterly boring and while the pay is not
too bad ($15/hr), we have no savings, nothing set aside for retirement. At this rate, I'll NEVER be able to retire. I'll work till I drop. If I'm going to do THAT anyway, why not do something that pays WAAAAY more than I'll EVER earn as a bookkeeper?
I will agree with some of the other posters in that you need to decide what you want: MD/DO or DVM. That should be first on your list. In order to decide, you REALLY need to do some shadowing of both physicians and vets.
If you decide to persue medicine, start volunteering somewhere. It doesn't have to be medically-related. It can be your church, a soup kitchen, tutoring, etc. You could even use it to bring your family closer together by involving your family as well. Mainly, it shows that you are willing to give back to your community. Wherever you decide to volunteer, make it MEAN something. In other words, don't let it be just a tick-mark on your application.
As far as your prereqs are concerned, many will say you HAVE to take them at a 4-year school. While many (perhaps even most) schools PREFER that, it's not an automatic rejection if you take them at a community college. Medical schools are cognizant of the fact that it's not always possible, particularly for nontrads, to take them at a 4-year school, whether from an inability to pick up and move to within commuting distance or job constraints that keep you from taking classes during the daytime.
And by the way, regarding your current lack of math and sciences: Don't let it bother you. I was a voice major the first time around in college. Until I started back to school at 48, the last math or science I had taken was in 10th or 11th grade. Except for my initial class (college algebra) where I had to get back into the swing of studying, etc., I've had no real difficulties. In fact, I LOVE being back in school and I chafe at the unfortunate, but necessary restrictions work places on me.
One other thing, be sure to listen to njbmd and Law2Doc. As she stated, njbmd is almost finished with her surgical fellowship and Law2Doc is a medical student. And since he successfully made the transition from law to medicine, what he tells you should be particularly apropos. I'm unfamiliar with the other posters who are currently medical students or residents. Several of the posters on this thread (including myself) are premed and thus, our comments should be taken with a grain of salt.
Best wishes on your journey. Let us know what you decide!
