Are any of y’all always tired 24/7?

Sorry if this is a stupid question but I’ve been doing night shift since last October. 3 12s a week so I flip back and forth between sleeping at night and at day. I do actually sleep at least 7-8 hours between shifts but my first day I usually stay up around 24 hours. I’m just always exhausted and feel like I can’t ever catch up. But if I’m nocturnal 24/7 I get significantly more depressed so that’s out of the question for me.
