I'm moving onto a new chapter in my life (moving to the big city, change of occupation, etc) and whilst I'm excited, I can't help but feel strangely sad, too. Have you ever felt this way about moving onto a new area in your life (literally and figuratively)? I hope this feeling passes soon.
yes, it's normal to feel lost around the time of moving, even if it's a positive move. it should hit you hardest when you pack all your stuff
