My hubby cancer may have returned ,we will find out next week. He is a combat wounded veteran, with many health issues and PTSD. After 50 years of marriage, I have fine tuned some survival methods of my own. That said, they don't really work well for him. But, here's what I have done. I keep good records, I have a file for after he passes of paperwork to be done for vet benefits, necessary documents, banking and ins. Etc. All the stuff you will need to decide on later, decide now! With a backup plan. I also have a sewing, craft room set up, any hobby will work. I've always wanted to play piano, so bought one and am teaching myself. You need at least one good friend who will listen objectively, I went so far as to buy another puppy to keep my mind from wandering. Basically, I find out what will or may happen, decide how to handle it, and then put it out of mind until needed. I keep a few nicer outfits on hand for Dr visits, I find that being well groomed helps you look more intelligent, and you get better responses from others. Shouldn't matter, but most people only have a few minutes to judge how you will respond to all this medical technical jargon, it's best to get on their upside right off the bat. I know you must be scared, this is overwhelming at best, and you have so little time to prepare. Make yourself a notebook and write every thing, even thoughts down. Take time for yourself, sounds impossibly cliche, have a glass of wine, or a beer, whatever will relax you for a minute. And most importantly, pray for your husband , yourself and be thankful for each other.
