I think that part of what you are feeling is physical, mental and emotional fatigue. Who wouldn't?
Physically going through everything involved in a move is not for sissies- you could probably write a book about that, right? But sooner or later it will all be behind you.
Mentally, a million things are flooding into your brain. Check-lists nag too, just as you are going to sleep, I bet!
Of course they are, YOU'RE in charge!
Emotionally, any change is challenging.... you know that from your accumulated life experience. This move may be a little bigger than some changes/ challenges you have had in the past, but you have the DESIRE. That's the fuel that will help you make manifest what you happily envision.
You are experiencing a mixed bag of excitement in starting up a new home in a new location, new and fun possibilities- and- letting go of some present things, familiar routines and favorite people.
Remember- those favorite people could also experience change one day- just because you are leaving, doesn't mean they will permanently stay where they are. You see?
All you are feeling is a normal reaction to change. You feel it more profoundly when you are fatigued- but you can decide to be kind to yourself- in increments if that is all you can muster right now. It is allowed- and prescribed by me.
Honey, you could do brain surgery, if each step were small enough to handle.
Carpe the heck out of your Diems- with joy!
You're gonna love it here.
