Oh crap, Vicki. There is such a lot to learn so don't beat yourself up if you don't have the language down pat and a total understanding of the system in the next couple of weeks. BC is a long haul, regardless of what stage your disease is once you realize your world has turned upside down.
The wait for things to start happening may seem interminable, but juggling theatre lists, getting the right specialists all lined up and, most importantly, making sure you have the basic information needed for you to make informed consent can take time. You only get one crack at some things and it's so in your best interests for everyone concerned to dot I's and cross T's. Even though you will find there have been things that are overlooked or stuff that hasn't been done in what feels to you like a wretched lifetime of staring at the phone, there is a process to be followed and as @Afraser says, 'It is what it is.'
Good luck. Marg
