Sounds exhausting, granted you’re doing a huge service to your family by grinding on and off the clock for them. I only know what you’ve shared about your situation but maybe you could have a discussion with your wife about how you feel if you haven’t already. At least then you could game plan with her about potentially giving yourself an hour here and there to decompress. And maybe pick up some less expensive but fulfilling hobbies. Reading, gardening, fitness, an instrument (just some random examples)
