You are entitled to a pity party, we all have been in your shoes. Sorry you are having a tough time...
But hooray for you moving through chemo so well, half way done! That is a big hurdle to cross! As for Her 2 status, I do not know much of the details about
it, but the very good news about
it is that Herceptin is available in the adjuvent setting now, for early stage BC. I think mine was a 2 out of 4, which was considered borderline positive. In 2000, when I did chemo, herceptin was only available for Stage IV cancers, in most cases. Now I think they give it for stage I or II, and the results are supposed to be pretty amazing as far as keeping people disease free.
And being ER+ is a good thing too, not a bad thing! It means you have an arsenal of hormone receptor medications that can also keep you disease free or slow progression of cancer.
And try not to let statistics get you down...they are numbers that predict the overall outcome, but no one can say how you will do...
Hang in there!
