You need to remember that there are many different parameters to take into consideration when choosing a career such as future pay, interest, lifestyle and more. Every person has different priorities and therefor ranks these variables in different order.
If I were you I would sit down and make a list of topics I felt I enjoyed during my BA degree. After you do that you'll have something to work with. Then you can try to find out more about the different options you wrote. Talk to different people who are already working in the fields that interest you and see if what they're doing appeals to you. perhaps you can get a job in an area that interests you and that way see how things work there.
The bottom line is that being confused at this stage in life is natural. It's not easy but hopefully in the end you'll find your way.
