Yep, it will be easier once you get started. Move some easy stuff. Then you'll feel like you have accomplished something. Can clothes on hangers just be carried upstairs? Cleaning the closet out--putting that in the new place is a good start. How much time do you have to move?

How about the fridge and kitchen cupboards? Take one box, fill it, move it, unpack it, then go back for another. So the new place will be put in place, what you've moved. Might help you feel more settled.

Just put one foot ahead of the other. Take baby steps, but do move. It will get easier once you've started. Wish I could help more!
