Honestly might be that same mental affect that happens when you have to use the bathroom, but the second you get home you REALLY have to go, it’s like your brain connects a certain feeling with a location like it sets something off, maybe home is a place where you got to rest a lot and it’s a comfort and your body knows you need rest so it’s reacting in that way? just a guess here tbh
It happens to me all the time. I had notice that when I used to practice exercise I was feeling more into doing much more than now. Everything is the belief system. There is a belief in your mind that allows you to feel overwhelmed with that feeling. But it takes time to train the mind.
