Oh Clare, My mum also has Parkinson's disease,she sometimes talks about coming out to Australia but the truth is she very rarely leaves the house now and when she does she has to be accompanied by someone, she is only 62 and needs assistance with most things able bodied people take for granted.
So even when people have been well meaning and said she'd be alright ............ I know myself that its not going to happen and I wouldn't want her to make it all the way here only to spend all her time dreading the Journey back.
Things will improve for you I guarantee , the summer here is beautiful and throws a very different light on things , I cant wait to get down the Beach after work with my little lad and have some fun.
All the best
