I'm in a similar boat. I had a startup, connections, was featured in the right places. I got married, and my wife had complications.
6 weeks in the NICU, wife's health has only gone down hill since. Now I'm running between programs for special need for my twins.
From time to time, I struggle with my dreams, but I'm also pretty good at lying to myself. I still manage to get things done to advance my dreams.
Make sure you look after your own health too, if you lose that it’ll be a lot harder to help those around you.
If you want to chat I'd be happy to reach out (I see the email in your profile).
I'm trying my hand at a startup right now, just to see if I can make a go of it.
