Recently lost my wife and my whole life feels like this listlessness you describe. Some suggestions people have made.

Plan out an hour after work to do something even if it means not driving home for an hour and going and doing something. This one works for me.

Do all your extra work on the weekend when you have the energy. Laundry and cleaning the house fit in here.

Plan out and prepare your metals for the work week on the weekend. Its only 5 meals. Cook two big meals and portion out the extras as leftovers in frozen containers then make an extra small meal that is either quick to cook or precooked or frozen meal from store. You now have three meal variety you can pick to quickly cook during the week after work. This works for me as the variety makes me feel like I have a good selection to pick from and if I buy some junk otw home I can eat the extra on the weekend.

Force yourself to exercise for at least 20m every other day. A hard sweaty workout! Just fucking do it no matter what. I do this in morning before shower.

Life still fucking sucks and I hate it… But its better than it was and gets better day to day. You just have to do it.

That’s really what it all comes down to and the only real advise. Just do it. Pick one and do it for two weeks. Then add one more and do it with the first one for the next two week. And repeat. They say it takes two to three weeks to build a routine. At some point it will feel weird to NOT do it… But it takes time and energy. So just fucking do it because its not going to magically get better on its own.

Just do it already.
