I work 9-5 and I will agree, sometimes it feels like a nightmare. I can't keep it up too much longer. Shit will slowly kill your spirit if you're not the type who can handle it.
And mine isn't even in an office. In fact my boss is a chill, laid-back motherfucker and I have what many would consider a dream job, working in a "media production" field doing high-profile video shit.
It's the schedule that makes the whole thing fucked. The monotony and the bleak outlook of returning to the same place 5 fucking days a week, earlier in the morning than you'd like to. Plus, for me and plenty of others, there's the shitty cycle of getting fucked up every weekend to try and forget about having to work, then coming back on Monday feeling like shit. Only to attempt to recoup through the week before doing it again. And when I try to be disciplined and stay in / sober on the weekend, I feel depressed as fuck. Because Monday is looming and there's no alcohol to make me forget that.
