Hi Hen -- sorry to hear about your diagnosis, but welcome to the site. I'm glad you found your way here.
I also just wanted to let you know that this is an older post, so it's possible the other network members won't see your comment here.
Best way to get an answer to your question is to make a new post in your own blog (see the link in the pink box on the right side of the page labelled 'my blog'). You can just copy and paste your post text again if you like, to make life easier.
When you post in your own blog, it will show up on the 'All Posts' page (which is here, if you haven't found it yet: http://www.bcna.org.au/node/all/blog/network), and anyone who has an anwer can jump in.
Hope that helps. :)
Di
