Feeling torn between two homes

I’m sure I’m not alone feeling this way. I’ve been living in the US for a little under 10 years, originally from Australia. As I enter my 30’s, the gravity of my choice to uproot and move across the world far from family and friends is dawning on me. It was so easy in my early 20’s to get up and move! I love my life in the US, but equally love Australia and my family and friends there. I’m afraid I’ll never be able to leave the US out of fear of losing everything I’ve built, but I’m equally afraid that if I moved back to Aus I’d have to start from scratch.

Not really looking for answers, just wanting to know I’m not alone!
