Rhinoplasty scheduled in 3 days… feeling nervous and overthinking

I’m 19 and I’ve been insecure about my nose for the last 5 years. Whenever I post anywhere about getting rhinoplasty it’s just people telling me not do it or that I will 100% regret jt later or lose my “uniqueness” or “character” or that it’s a “shame”. Currently I cannot stand my nose right now and hate seeing photos of myself from the side especially when I’m smiling because it just makes me depressed. I know that when I see myself in these photos and don’t like the way I look that it is not just with my nose and I have a lot of other insecurities with my jaw and even parts of my face that I cannot even change surgically if I wanted to but the nose is definitely a contributing factor. I’ve been hell bent on getting rhinoplasty done as soon as possible but now days before I’m worried that even if it goes exactly according to plan it’s gonna make me look worse. I’m 100% going through with the surgery, none of the comments are ever going to get me to change my mind but they just are making me overthink and stress out and be even more insecure. I don’t want to look unique or special I just want to look better. The morphs look better to me and don’t care if it makes me look better to others or not, I just don’t want it to look worse to other people. I already know I probably have a lot of mental issues with my appearance and trying to fix them with surgery is probably a bad path but I’m 100000% committed to this rhinoplasty and it would be at least 5-6 years before I would be able to get more surgery so maybe I will be better by then
