I’m planning to have my first surgery…

Now that I'm a senior in high school who just finished the college entrance exam, I'm thinking about getting double eyelid surgery either outlined or semi-outlined, but I have no idea where to do it, and I've already made reservations at three plastic surgery clinics for Friday, but I'm not sure if I can decide right after the consultation... I'm so worried ㅠㅜㅜ I'm so anxious that I might make a mistake, but I really want to get double eyelid surgery... Can anyone who's already had successful double eyelid surgery tell me where and how they did it??? The more cautious I become, the scarier I get ㅠㅜㅜ
