How to deal with a frankly terrible work life balance?

I graduated a couple years back with an engineering degree and now working in a large city in the construction industry as an engineer.The first year or so it wasn’t that bad as I would show up to the office around 8 and leave around 5:30. The commute was about an hour each way by train. Over time, the hours have really geared up and I’m having trouble dealing with it on a mental level.I was always a hard worker, had a great GPA in school, internships, programs and volunteering, etc with time for a couple of intensive hobbies too.Now I feel like my life is either work, or not work. Weekday or weekend. It’s so depressing. No more hobbies unless you count video games and the odd weekend trip to fish or hike if the weather is nice enough.To be fair, since covid my department has been WFH which is for sure a godsend and I’m grateful for that but I’ve been working more from home than I was in the office. Most days I don’t log off until 8pm or so (with some days until 9 or 10pm not to mention a hour each weekend day to catch up on emails). It’s just so weird because I feel guilty for being stressed out when millions are out of work but I can’t help it.The 12+ hour days looking at a screen and taking literally upwards of a few hundred phone calls and conference meetings a week is really taking a toll on me. Not to mention the tight deadlines and high demands for quality of work.Don’t get me wrong, I feel incredibly grateful for my job/career as I’m paid well for my age and coworkers are all awesome human beings (it’s really the clients and industry partners that are scummy with the deadlines and demands etc) but I just don’t know how much longer I can be productive and sane.The job itself is just so stressful and fast paced (which I’m completely okay with) but doing that for 12+ hours a day feels a little too ridiculous. Not to mention I’m in NYC so my apartment isn’t that big and I feel trapped (even with regular walks and getting outside on the weekends). I literally sit in the same chair all day...Any tips or words of wisdom? Am I being unreasonable?
