Hi, I'm so sorry you have to go through this, like yourself I had the same diagnosis 18 months ago, unlike yourself I told my daughter straight away because I wasn't sure of the outcome but I was told at the diagnosis what my plan would be and felt confident enough to tell her said plan that she could cope aswell, do take the time to get your own head around this first though, no one but others going through it know what your mind is doing at the moment. I understand completely, where if you don't mind me asking is the secondary in bone structure, I'm asking because mine was in hip/pelvis and spine and resulted in hip replacement which I found although a few weeks on crutches not too bad, this followed by targeted treatment therapy for spine, I must say it's a lot to get used to in the moments but your mind can do wonders and once it's sunk in you will feel you can deal with it and carry on, I wish you the best with your treatment going forward and once your family know they will I'm sure help you with your journey, take your time try to do a little bit of what you fancy to take your mind off it for awhile when you can. x 

Thanks for taking the time to reply, the Dr said it's in my pelvis and spine, they don't yet know where the primary is, I think I'm trying to bury my head which isn't like me, I face things head on, but in fairness I've never been through this or anything like it myself, my hubby has prostate cancer last year, he's doing well thankfully but I'm worried sick, I'm glad you're doing well
