Hi
I thought I replied yesterday but perhaps I didn't do it correctly.
Don't lose hope, trite as that sounds.
I was diagnosed almost 10 years ago, also with stage 4 and I am going strong and doing well. The biggest interference with a normal life are medical appointments and less energy.
The treatments you are on are tough but most of us seem to have started the battle with those. I only recevied them when a recurrence happened almost 5 years ago. Initial trmt was radiation followed by megase, the later a major waste in my case.
Hang in there and enjoy your life!!!!
