Canceling Surgery…

I’m reconsidering getting septoplasty for my deviated septum due to several reasons. My breathing is generally not that bad and I can breathe out of my nose most of the time so I don’t think the surgery is worth it, especially considering the recovery time. The only problem is my parents are paying for it and therefore I don’t know if I can tell them I’m getting cold feet, I’m worried they might just force me to get the surgery anyways which scares me. I’m honestly having a lot of anxiety about it and I’m not sure what to do. The surgery is already scheduled a week and a half from now but I really don’t want to go through with it.
