Does working full-time have to drain you?

I used to work 4 days a week which was doable because I had an extra day to rest. Now I've started working full-time. I'm a school based SLP outside of the US. Monday, Tuesday, Thursday and Friday it's 8 AM till 5 PM and Wednesday it's 8 AM till 2.30 PM. I come home after a 30-40 minute commute and by that time it's almost 6 PM. I fall asleep on the couch after dinner, shower, prepare lunch and go to bed till I wake up at 6 to start all over again. How do I get more energy? I mean, 12 weeks of vacation are great, but some joy after work would be nice too. Or am I just a lazy gen Z who has no work ethic? How do people enjoy their lives?
