Hi, Melissatonystahl ~ (that's a mouthful!)
I'm sorry you've received a diagnosis of acoustic neuroma/cyst but they are almost never malignant or fatal (if addressed) so there is that. The neuerologist will review your situation and make what he/she considers an appropriate recommendation how to proceed, which might mean surgery.
Please do not allow yourself to be frightened unnecessarily. The ANA discussion forums are here for support. That being the case, we have a lot of posts that are related to post-operative issues but most resolve eventually, people cope and life goes on. Some AN surgery patients have few problems and enjoy a good recovery. I trust you'll be one of those. Meanwhile, learn what you can, feel free to ask questions and try not to obsess over the 'what-if's'.
Please try to keep us updated following your doctor consultation. Thanks.
Jim
