It's actually very difficult to put into words why you want to be a doctor...
I think it's more of a feeling.
So no one can tell you if you should study medicine, that's a personal choice, which I hope you'll make your choice for the right reasons! I only made the decision after growing up a bit more and finishing my degree and traveling a bit!! And then I did voluntary work, shadowing and a HCA job before I could say for sure l wanted to be a doctor.
I wanted to be sure, no point in Working hard to get into a career that I would hate, and to study for another 4 years and get so so much debt for silly reasons like money (doctors don't even get paid THAT much, easier to make money else where) or respect (doctors have lots of respect, but so do other careers)
