Thank you all so much for your messages of support on my last post. It really did mean a lot to me. I'm not one to let those sorts of things out, I like to keep things all positive, all the time, but sometimes a girl's got to vent. So thanks for listening!
After writing that last post and hitting publish, it was enough for me to make the decision to get a little more proactive. I had been at that point of throwing my hands in the air and giving up. I've managed to track down a company on the Gold Coast that normally doesn't hire the batteries for the oxygen concentrators separately, but they have decided to hire them to me, at a fraction of the price originally quoted through the hospital. Not only that, the showroom on the Gold Coast doesn't actually have those batteries in stock, they are having them couriered up from Sydney for me, at no extra cost. As the machine I have is an older one, they only have 2 spare batteries, which will be an extra 6 hours plus the 3 I already have, which makes me feel a lot better about travelling. It will mean I will be able to have a small sleep without the fear of waking with a debilitating headache. It's nice to know there are some people out there willing to help you out.
Really, thanks again for the support, you guys rock.
