In my opinion you definitely shouldn't do medicine.
I dont have family who do it, but I want to, and I can only say that its the whole lifestyle (as well as the academic appeal) which draws me to it. And so many people I've spoken to (of course, you have your parents) say that its simply not worth it if you don't like the sort of life style you will lead, even if you are drawn to medicine for say academic or social reasons.
Before I looked at Medicine, I looked at Bio Chem, Chem Eng, Neuroscience and Molecular Biology.
Hope that will help.
Maybe Vet Science? My parents keep asking me whether I want to do that or not! (I grew up on a farm..)
