Why are you working long hours? Who is telling you to do that? If your manager expects you to work long hours, then your manager sucks, and you should start looking for a different team. If you expect you to work long hours, then you need to change your priorities. Decide how much work time your life can sustain. Set your hours and stick to them. If you do a reasonable amount of work at a reasonable pace, and the project falls behind anyway, that is not your problem: it is the project manager's problem. They can find more resources, change the scope, change the schedule, whatever they need to do; that's literally their job, and not yours. It's certainly not your job to magically bring an unworkable plan into reality through superhuman effort. When your work is done, turn off your work machine, log out of email, and go do something else. Do not open your email until you are ready to start working again: dealing with work mail is work.
