It’s completely normal to be nervous, especially as it sounds like your income and work is related to your appearance.
We all have our freak out moments, usually a meeting with the surgeon diminishes those concerns. Of course there is always the chance something could go wrong with how they end up appearing which for some of us doesn’t matter as we can still earn as much money until we can get revision surgery. It sounds like it might affect you negatively financially if something went wrong.
Make sure it’s the right choice for you career wise and if it is then go for it and do what makes you happy. Your consultation with your surgeon will make everything clearer and reassure you, it did for alot of us xx
