I don’t think you realize how lucky you are to first of all have the financial freedom to fly to Spain, and pay for a top surgeon, second of all how lucky you are to be booked with one of the top surgeon in the industry.
This has been at least 1-2 years that you are planning this surgery, I don’t get why all of a sudden you are rethinking everything.
people already answered your questions, answered your doubts, what’s the issue now?
you are overthinking it, and for sure your results won’t be any good if you over-stress everything like that.
