Metastatic Her2 Breast Cancer

Hi I was diagnosed 3 years ago with metastatic Her2 Breast cancer with bone mets. I chose not to ask what stage I am at although i am pretty sure I know. I am on permanent treatment of Herceptin and pertuzamaub every 3 weeks to keep it from growing. I think the hardest part now is I have been told I can no longer work this has made me very sad.
