Hi Robarts Family - it's such a difficult situation. I feel your pain. We initially came out to Oz in 2005 and lived in Wollongong. We lasted 3 months. I hated it and could not adjust. Hubby was happier but I eventually dragged him down. I was also pregnant with my 2nd child and wanted to be closer to family. My father also sadly had passed away. We started a new life in Horsham (never lived there before) with relatives in Kent & Germany. I liked Horsham very much, but we felt we needed to go back and at least get Australian citizenship. We decided to go to Melbourne this time and settled much better. Hubby lost his job, got a new one and we moved to Brisbane. Hubby lost his job again after 9 months and we moved back to Melbourne. We've been here for almost 6 years now. It does make a HUGE difference WHERE you decide to settle.
We now have a possible opportunity to go back to the UK, but it's a difficult decision. I am also very fussy about where to live in the UK. There are certain areas that I simply would not consider as I know I would feel depressed. If you're in a horrible area (and they are plentiful in the UK), it might be worth considering moving somewhere a bit nicer. I'm sure it will help you & your family to settle back into life in the UK. Good luck!
