Hi Laura, I'm from WA too. I have just done a google search on your condition & at least it is a fairly common occurrence & treatable. Where in WA are you & what treatment has your oncologist started you on?
It will be hard being so young & being diagnosed with cancer but as I said from what I have read yours is common & treatable so hopefully soon for you it will all just be a thing of the past & you can get on with your life & finish school.
This is a good site where everyone helps everyone in what ever capacity they are able to so make the most of it. If you want to talk just send me a private message.
