Hi Lynne48, what a difficult time this must be. But how brave and thoughtul of you to tackle it head on. I too am the main income in my household, and while I seem to be OK (touch wood!), the thought that things might go sour again is never very far away form any of us.
First thing is the good advice you have heard from others - there are many stories of women living with mets and making the most of their lives.
Taxol is found to be easier that many other treatments by many women - it can have a few annoying side effects. I lost my taste buds and got a susceptibility to nose bleeds - it's hard on the soft tissues - but it helped me lose weight, so a bit of a silver lining. I worked throughout A/C and Taxol.
I started making my funeral plans etc about a year ago (4 years after diagnosis, I don't rush these things!). I am 72 and it's taken cancer to convince me I am not immortal! Both my parents kindly recorded what they wanted - saved no end of concern and uncertainty, so I think it's worth thinking about - well or not. But this is best done when you are not revolving in a state of sadness or loss. I found talking to a stranger (a counselor) for a short time very helpful - not about having cancer, but having a changed notion of who I was with a few long term side effects. It helped immensely to accept the changes on a practical level but not feel that the essential me had to change.
I hope you have some support at hand, but always reach out here. Very best wishes.
