Dreading work

I have been dreading work lately and it's upsetting me because I used to feel excited about work. I'm worried I don't look happy to coworkers even though I try to smile and say hi to them I feel like I don't really want to be around anyone.

Has anyone else gone through this and what do you do to help yourself through it? I'm in e-commerce.

I have been a part time shopper a long time and I think maybe it's burned me out a bit as my schedule is all over the place and I pick up a lot of shifts.

Even the 4 hour shifts feel like they take forever and the 8 hour shifts I'm assigned sometimes feel like such a big undertaking even though 8 hrs is typical for millions of workers around the world.

Lately I wake up and I feel my body just wanting to stay home and dreading going to work. I wonder if other employees feel this way.

Anyway just wondering what other people do to get through this
