I recently went to my pdoc with the same problem. I am finding it extremely hard to get off the couch, have showers, or find enjoyment in things. He says it sounds like depression, I told him Im not sad, have no other symptoms so I dont think it is. So then he said he has no idea

I was thinking my AP might be up too high so I might experiment with dropping that down but I cant just yet as I have a few things to work out first.
In the mean time, I was pushing myself before, but now I am pushing myself even more. Its really difficult, I dont really enjoy the activites that are off the couch so why should I move? But I know that activity helps with motivation so I keep pushing and keep doing things hoping that the motivation will come. I feel proud at the end of the day if I have achieved something, but as yet motivation to do more is not there.
Goodluck.
