I am sorry for what you and your wife are going through. I remember feeling a range of emotions, shocked, scared, disbelief, sucker-punched, as well as feeling numb and like I was in a surreal world.
You actually both need support; and it will be hard on you having to be the brave one. Give your wife lots of gentle hugs, and you can't say I love you too often.
While each situation is unique, a lot of people on this forum have dealt with cancer involving themselves or family members. Please feel free to reach out.
