Well I've told my wife who told her mom & dad, and sister & bro-in-law, and I have told my mom & dad, and my boss obviously to get the time off work. My Boss is very supportive, as I have known him for 10yrs so that was awesome. I feel I need to tell my siblings, 2 brothers & my sister. But not sure when or how.
I have also told my best friend he's been around since I was 2, so he was super supportive.
I have my doubts every now and then for a few seconds, and then I remind myself of why, and I'm good to go. I have a surgery date, but just waiting on approval which I should get next week, and then I will tell the rest of my family. And maybe my other best friend(he lives far away, so hardly have the chance to see him).
