It's hard to come up with a specific answer for this because everyone is different. I think you might be better served by asking this same question to a qualified therapist who can help you work through it. It could be as simple as "You need to force yourself to get up and get more exercise" or as complex as "You have clinical depression and you should be medicated if you want to feel normal again".

For me, I used to feel the same way after work. I would just come home and veg out, not care about much of anything, and take very little joy even in things I liked. The thing that snapped me out of it was my failing health causing me to be forced to switch up my diet and go to the gym a few times a week. It wasn't easy to get started, but once I was about 2-3 weeks into my new routine I was feeling more energetic and motivated. I noticed I was getting better sleep too which made me feel ready to tackle the day every morning that I woke up for work rather than dread going in.

Again, your mileage may vary, I would strongly advise to speak to a doctor if you are having difficulties with this issue to the point where it's negatively impacting your quality of life. Don't put it off until your health is impacted like I did.
