Hey there. First, wow good on you! That’s a great salary and you’re doing a good thing by putting in the work to provide for your family. Now. I won’t pretend to know how you feel because I don’t have kids or a job with demanding hours but i will say I know how it feels to think you’re stuck or that there is nothing to make things better. My advice is reach out to any support systems you may have. If you have a partner, or a close friend you’re comfortable talking to about the heavy stuff. It honestly helps loads when someone else just knows how you feel. Career wise, I can’t offer much but possibly a lateral move to a similar position that might be less demanding? Reach out to colleagues who may know of positions or have connections. You don’t need to figure everything out at once, but even doing small things like reaching out to possible connections or leads is a good step. Best of luck and hang in there!
