What scare you about moving around?

Hey everyone!!
I' m making a survey about expats lives, and I'd be very glad if you can post something about your own experience. I' very simple, just one line to complete the sentence:
What scares me most when i'm moving is....

It doesn't matter the reason why you are moving, may be because of you work, personnal decission, to travel...What's important is that you are leaving your home to start a new life in another place.
Thank you all and feel free to contact me in case of any doubt!!
Regards,
Eugenia Jantti
