How do you have a life outside of work?

I have so far been at my current job for a year and a half. It's full time. My shifts can vary between 8 and 12 hours. I basically do not have any free time outside of work. I go to work in the morning and when I get off from work everything is closed early, due to covid, so I pretty much shower eat and go to bed. I may occasionally fight my sleep to stay up later. 

Last night I fell asleep around 11pm and woke up around 11:30am. I pretty much slept all day. I didn't gain any energy until 6pm and it's now almost 11pm. This happens anytime I am off from work. I sleep my day away and it's annoying.
