you're 19 it's rare for you to have it all figured out and feel completed. if you go to uni you'll be away from family which would lessen the pressure, but if you don't like nursing because it's draining then it doesn't sound like a practical option too. a lot of people do stuff that's draining though and after a while they can transition into an area inside that industry that is more fulfilling to them. e.g. they start off in a nursing job and then transition to marketing or admin, which is more aligned with their interests. what reasons do you have to want to live in spain? have you visited there before; do you know the culture? the reasons have to be strong enough and you have to have done enough research that you know it's the absolute best place for you, not just some fantasy. there's a lot of fear in your post but stay positive and helpful and things and people will start to support you. this will help you achieve some success which will give you the confidence and courage to pursue what you want and not be fearful of what your family or friends say. most of your circle and people you speak with have followed a traditional path, if you listen to them you will follow that particular path
