Oh Celeste! I am so, so, so upset for you. Like you say, how can they give you that false sense of security and then land that on you. I wish I was there to give you a big hug.
The cancer in my bones spread quite quickly too while I was on Tamoxifen (which obviously didn't work) but seems to have slowed down considerably since my switch to Femara. Mine is hormone positive - I haven't had any chemotherapy yet - just hormone treatment.
I will pray my hardest for you. You are such a beautiful soul and I do believe miracles do happen. I hope the new drug regime will prove to be your miracle treatment.
My love to you and your family at this terribly difficult time.
