You will find lots of help here pixie, for your mum and dad and also for yourself. There are a whole series of factsheets which would be a good start, but just come on to the forum and ask whatever you need to as there is a wealth of support and kindness here.
It's an incredible shock to receive the initial diagnosis and reading others threads can be very frightening, but do remember that everyone is different. Your mum must be so frightened too, but having you to support her and to be able to answer her questions and share her fears will be a great help to her. xxxx
