So much has already been said, but I just want to chime in that you've done amazing things, and it's not surprising that you would feel that post-adrenaline let-down. It happens with other things in life, too, where there's a huge build-up, a huge investment of mental and physical energy, time and work, and then when it's over, it's like, what now?
I think that's when it's a great time to do something to treat yourself (and your family), to breathe deeply and stay the course. Take a little break, find a distraction, a neglected project, and then later you can think about what might be coming with a clear head and shifted priorities.
Honestly, in the past, I tended to get sick after something super huge was over. Like the adrenaline kept my immunity strong, and then I would crash. So take care of yourself, exercise, eat healthy, be mindful, be relieved.
