I know it's difficult, but do take care of yourself. I'm not sure where you live, but we prioritize work over life too much in many places (America, Japan, probably several others).
A healthy job in my opinion allows you to make enough money to not worry about your finances too much and enough time to enjoy the truly important things in life (family, friends, excercise, hobbies).
Everyone is different though and some people seem to really enjoy the stress of a high profile position (Ex: Musk) and many scientists that live to work. To each his own.
If you're feeling burned out, consider trying a new job. If you're in Silicon Valley, you can likely find a good IT job in much of America that pays well in a probably much cheaper area and that allows you more time to pursue a better work life balance. Personally, everything changed for me when I became a Father. I still love my job and put in a lot of hours, but I take time to spend with my family too. Don't feel guilty about it.
