Hi Kelly,
I think it's completely normal to be feeling this way, I know I would be. Bone mets are a bastard but some people live a long time with bone mets.
You need to fight now kiddo. Keep yourself healthy and help your body stay strong for as long as humanly possible. There are new treatments coming out all the time. Don't lose hope.
There are dark moments, we all have them when faced with something as horrible as this disease. But there are light moments as well.
Take care of yourself emotionally as well as physically and always know that we are here for you.
Sending you big hugs and love.
