Many of the non-clinical specialties allow a 9 to 5 style of working such as public health, pathology, forensic medicine, medical genetics. There are numerous niches for doctors in the civil service, medical ethics, education, journalism and the law. These are not mentioned in your training and require a bit of researching. It is virtually impossible to avoid exams altogether, but general practice is probably a more friendly place for the exam-shy. If you are really terrible at exams and vivas, don't saddle yourself with a career that involves regular bouts of misery.
Every branch of medicine is full of possibilities.
Each branch has its own history and culture. Even within general practice there are diverse options. You might chose a remote rural practice with a cottage hospital where you can practice independently to a high degree or you might prefer part-time work in a deprived city centre caring for ethnic communities and doing research and teaching in the local medical school. There is something, in short, for everyone. It is important to consider all the options and to do as much research as possible before you commit yourself.
