Hey man,
I wish you and your wife best of luck, but really try to keep calm. You really do noone a favor when you are agonizing day in and day out. Keep doing things you can influence while this time like for example doing nice things with your children, but don't try to do everything. Keep cool so your wife is gonna have a cool husband when she comes out of operation room. (and not an exhausted something =P take you the time you need)
Besides, noone will judge you for prefering your wife before Mythruna.
Wish you, your family and especially your wife best of luck ! But I guess you already did everything you could =)
Keep cool
