Am I the only one that feels this way?

I know some people will say that I should talk to a doctor about this. But I want to see if other people feel the same way.

So basically after I get home I feel really tired and it's not like I work crazy hours. I got moved to part-time unfortunately but before I'd be working 11-12 hour shifts but now I work really short ones. But my parents think it's not normal because they didn't feel like this at my age of 20. Like when I'm not working I'm pretty awake and going out and stuff. Like I get pretty good sleep I sleep like 9 hours every night. My diet is decent. So I want to know if anyone else is this drained by work as i am

Am I the only one that feels this way?
