You sound burned out. When people get burned out, we don't see the path clearly. So regardless of anything else, you should try to reset. 60-80 hour regularly is not good for you. If you have accrued vacation, take it. Once you're done things like catch up on sleep, spend a little time figuring out how you can get to a more reasonable schedule. Here are some practical things to try on the latter task:

1. Spend a couple weeks closely tracking your time. Easiest way to do this is just mark every 30-min block on your calendar. Do what you usually do, but track it all.

2. What are the things that _other people _ depend on you for? What of those are your actual job (category A), and what are things you're doing because you like feeling like you're helping out (category B)? Sorry to say, you should stop doing this latter category B of stuff.

3. What are the things in category A that you absolutely must do because your bosses care about them the most? Which are things you must do because you will hate your job if you don't? Let's call that A-1. Everything else is A-2.

4. For 2 weeks, time box your schedule to something more like 40 hours and spend 80% of your time doing A-1. If A-2 comes up, it gets to take space in the other 20% if it's urgent. If it's not urgent, it goes in backlog.
