I’d ride out the living at home as long as you can and start your career doing the subject you enjoy. It’ll make you feel better about working. Although one internship is paid, if by the end of it you feel jaded and fed up because it’s not something you enjoy, you’re going risk disliking it before you even get the chance of doing it for real in areas you like.

I know it’s fun to think about moving out / being independent etc, but it’s tough and there’s no going back to what you have today (it’s never the same). Defo take the gap years too and prolong your youth and lowest level of responsibilities you’ll ever have again, for as long as you can.
