I'm keeping mine a secret as well with the exception of my SO and potentially my kids once I get much closer to surgery day. I don't even feel like I can trust my Mom with the information.
As I've matured I find that I need the approval of others less in order to feel validated. That being said, I really don't want/need others opinions regarding my health choices. I don't want others re-telling versions of my health choices either. I think we all know that folks who haven't spent time in our shoes can be quick to judge or comment on something they can't possibly understand. Even those with the best of intentions can hurt or make you second guess yourself.
I've considered this step for two years now. I know what I want. I don't think there is anything wrong with keeping such a private medically founded decision solely your own. I only worry a bit about support at times but I feel like this is my life style change to make, not everyone else's. I have to figure out how to make my way in this new lifestyle. I would love to hear what others are doing for support if they aren't telling family and/or have weak support systems as that will be something I will need to prepare myself to deal with...
