RE: Had I not been a doctor, What could I be?

That's a very interesting switch of profession hehe! I think unless we try something out, we won't really know whether we are good at it or whether we actually dislike it. And that seemed to be the case for you isn't it! Or do you still dislike sales? 😄

If you still have the passion for IT, I think you shouldn’t totally abandon it. Maybe do something in that line as a hobby and not look at it as a job.
