I'm not in your shoes, but I'd happily trade places. I assume you're calling most of the shots, so if you take a step back and reflect, where is this stress coming from? Who is putting pressure on you? I'm guessing it's you doing it to yourself because you hold yourself to a high standard and have a strong work ethic. Excellent qualities.

So take a few days off, refocus, slow down, and just do what you can do. No pressure.
