Stage 4 breast cancer treatments

In October 2017, I was diagnosed with stage 4 metatastic breast cancer at the age of 35 right before my 36th birthday.  I had very aggressive chemo treatments and I have been in remission since February 20th.  I am HER2 positive, so my treatments will have to continue forever.  My support has been so strong and I am fighting my fight and so far...i win.  The treatments are very costly and it's difficult to keep up or even try to get ahead.
