I think you will be able to manage with these subjects. But make sure that you are able to fluently speak and read in English. Also remember, if you really really really (like really!) enjoy the subjects you have taken in HL then continue with your options. And I don't really think it is such a great idea to take 3 languages because it might get very hectic for you. Maybe you can look into Business or Economics or Film (if you enjoy these subjects).
Also, make sure what subjects are required for the University you plan on going to.
All the best!
