Well not to be an ass, but why would you drive yourself around? I have the feeling your boyfriend and his family wouldn’t mind driving you around for a bit. And in Europe you don’t generally need a car to get around.

Anyways. Driving manual is not too hard. Just don’t let the stalls bother you. Other drivers don’t really mind either if you stall and waste a bit of time, so just relax. And to be honest; I would actually take the chance to learn it while you can if I were you. Seems like you have a good opportunity here.
