Hi Fergie,
I know where you are coming from, we lived on the Gold Coast for near 10 years, loved so much of the place, our daughter was 13 when we arrived, during our time there we added two boys to the family, I didnt start feeling home sick for the first 6 years it was after our first trip home. Then in 2018 we moved back to the UK. I missed my mum so much (we were very close, we used to send her a ticket for Oz every year to come over to us for a couple of months) as time went on I too suffered terribly with anxiety, palpitations, tears upon tears, felt like I didn't want to be there. So we moved back to UK leaving my daughter over in Oz at Uni, with her friends, boyfriend, she too didn't want to return.
I arrived back with a hole in my heart, missing my daughter so much, its made me ill, in a way I feel like we made the right decision at the time, I managed to spend a quality couple of years with my mum, we crammed so many memories into a short space of time, but April last year she contracted Covid 19, unfortunately claiming her life. I feel very blessed that I could be with her right at the end, to tell her our goodbyes, and how much she was loved, I would never of had that had I been in Oz. but now I just want to get back to Australia, I don't feel settled here at all, I miss my baby girl too much, so do her brothers. Facetime, phone calls and WhatsApp is just not enough I just end up in tears when I hang up, so we are returning summer this year flights pending (fingers crossed).
So yes I understand you dilemma but for me, its not worked out, so I'm heading back,
Good luck to you x
