I wouldn't do it either. I'm another junior doc, ten years post graduation, who would have a cry in the cupboard if my DD said she wanted to follow in my footsteps. I love my job, I really do, but hand-on-heart I wouldn't recommend it.
Med school is great - the hours will be sociable (actually sociable), lectures 9-6 and placements similar. Some expect you to do a few night or weekend shifts so you know what's coming. Depending on where you study, the distances you will have to travel are variable (my medical school there were several commutes of well over an hour).
Foundation years are hard. No other word for it - long days/nights, long runs without a day off, the most junior person in the hospital and managing everything on the shop floor. Not by yourself but there will never be enough time for someone else to look over everything you're doing. You will make mistakes - how big and how bad they are is partly down to luck. You may not be working somewhere near your home - it's increasingly a lottery where your workplace is.
People will die, people will abuse you - verbally, and possibly physically. People will complain about you. All the time you will be giving your all - so much so that you will have very little left at home.
In amongst all of this, you will be expected to decide which specialty is the one for you. You will have to make this decision early in your career so you can tailor your spare time to give yourself the best chance of getting a place somewhere near your family. Even then, you will often end up commuting over two hours a day. Which, when your shifts can be 13 hours or more, doesn't give much rest between times. Or, you move every 6-12 months. But you can't do that to children.
All through your career you will have to pay to put yourself on courses, through exams and on study days - to show you're continuing to learn and progress. In your free time you will audit, you will prepare teaching and presentations, you will have to reflect on your practice and on events that have affected you. You will have to search for evidence to show you're competent, you will have to nag your colleagues to fill in paperwork (in their spare time) to show the same.
You may not be able to take a holiday when your family can.
You will work Christmases, birthdays, funerals, weddings and anniversaries.
If you still want to do it, go for it. But be sure.
