Since you love working at your current place, reduce your hours. That's it. Work less hours. You need to solve the burn out issue. Talk to your management and get a reduced number of hours every week. Do this for at least 3-6 months and see how you feel. Then go from there. You already know that 10M+ is fk you money. So you technically don't need to work at all but I know that people like you cannot just sit on their butt. So "compromise" with your inner calling and don't do 14+ hour days anymore :).
