It sucks for everyone. There is a ton if information out there from loads of people with direct experience. All of our stories are unique and yet the same, in the macro/micro sort of way.
Look on the 1st link for "The 180". Basically, indifference to your spouse. Be careful "researching", it always triggers.
Hydrate (water)! Make sure your body is tired at the end of the day to help you get rest. Seek comfort, comfort food, sunrises, sunsets... Scale and perspective.
You can never change/fix the past. It sounds simple but so much of our remorse is based on "if only".
Good luck, take care of yourself. When the oxygen masks drop from the ceiling, put yours on first so you're in a position to help those around you.
