I am so sorry that you have this news. I too faced this news last year and am still going strong with lung mets now nearly 18 months later.
There is an advanced Cancer group on here and a group of us on Facebook that chat and support each other regularly.
When you feel ready you may like to order the Hopes and Hurdles kit from the BCNA - it has been updated and has a lot of useful information.
It is absolutely devastating to recieve this news and it takes time and effort to get up again. Be kind to yourself, allow yourself to dwell a little and take check.
Sending you love.
