I have a passion for astrophysics (as you can tell my college does not offer an astrophysics major),
Do you know the 'difference' between astronomy and astrophysics?

There is one, but many don't bother making any sort of distinction any more.

..Do you want to go to med school? There isn't a worse reason to do it than 'because someone else wants me to'. It's your life and your career - sure, make sure that you're making informed decisions and do your research but taking a route you're simply not interested in, particularly with something like medicine, is a recipe for disaster.

They tell me there simply isn't a great job market for those majors. Is this true?
No, not in the slightest. Physics (and so astronomy) majors are extremely employable. The good thing about physics is that you'll touch a bit of many different fields. An undergraduate physicist knows a little bit about a lot of things - you'll learn mechanical, electrical, materials subjects and do things like programming, numerical analysis, modelling. The skillset you come out with from a degree like that is excellent. This means that physics graduates are in demand in lots of different industries. For instance, a physics (and astronomy) major can usually apply to all of the same entry level jobs as engineering graduates, on top of the physics focussed entry jobs. Then there are things like finance where physics graduates are sought-after. That said, the job market is a funny thing - if you're looking for something extremely specific then clearly you'll have a hard time getting it. But if you're looking for a job, then physics will give you many options in lots of different areas.

Am I really beter off going to med school? Thanks.
That's a question you need to ask yourself. Why would you go to med school? If the question is "if I continue with physics and astronomy, will I find myself unemployable for the rest of my life?" then no, you won't. If you have a physics degree, then you'll find that if you want a job, you can get one.
