I know the feeling. I’ve been in a similar situation before, and it’s one of the toughest things to handle. I literally thought my life was over. In the end, the whole experience made me stronger BECAUSE of it.
One thing that kept me together is to keep repeating myself that “it can ONLY get better now. No way I’m letting this grind me down.”.
Your wife and kids will understand. They’ll never blame you for trying.
