Stop working overtime, do the minimum amount of work necessary, and start looking for a new job. They've already stolen enough time from you in overtime work, so make sure you use your normal work hours to search for your next opportunity.
Also don't worry about the stock you own, it's a scam to get you to work harder for relatively small rewards (or more likely, none at all) at some future time, and it shouldn't be an incentive to put up with abuse.
Time with your family and your own mental health are the most important things here, not appeasing these petty tyrants.
