Hi Penny Rose,
I also have secondary BC. Which was my initial diagnosis... all I can say to you is to take each day as it comes. It can be an emotional roller coaster. I found for me it is important to focus on the present moment. And trying not to think to far into the future. I try and read uplifting books, and stories about people who have beaten the odds.
None of us know how much time we have left ( cancer or no cancer ) And even the doctors can get it wrong sometimes, and many people outlive their expected timeframe. Also there are so many new developments when it comes to BC. You should become a member of the metastatic BC group. I have found that connecting with people who have a similar journey is very helpful. Wishing you the best in health! Xo
