Please know there are people half a world away, who don't even know you, who are pulling for you and your wife and are sending positive thoughts your way.
Tell your wife there are some total strangers around who send her some love. There's plenty to go around for her family too. It is rough on the whole family and my thoughts are with you guys.
i'm so sorry - hope she gets better and you can both enjoy the break - unfortunately life does suck but it's the memories of living it well that keep us going
