Hello, I couldn't imagine what you are going through with moving from a new country and being sick. Australia is very laid back, but im sure you'll make friends soon enough.
Have you started school yet? I am born and breed Australian, originally from Queensland, North of Melbourne. Personally, I've moved all over the country with my family, due to larger family issues. Actually, my youngest sister is diagnosed with cancer, early last year. So my family and I are always back and forth from hospitals. I can see where you coming from, its even getting to much for my sister and she's only 5. I'm wish you luck for everything, we Australians are very accepted of new comers. Are you still in contact with friends in Scotland?
