Just over a year ago my daughter was diagnosed with bc(Initially Her2+ but confirmed after mastectomy also Triple Neg).
It’s been so bloody tough(physically and emotionally) for her and has had ripple effects for us all as a family.
Setback after setback keeps on coming. The gift that keeps on giving 
I’m so sorry to hear what your daughter and your family are going through.
It’s normal to feel a range of emotions when you’re supporting a family member with breast cancer, so it’s important you find support for your own physical and mental wellbeing.
Communicating with people in a similar situation can help so I’m really glad you’ve reached out here. There is an area of the forum specifically for friends and family that you may find helpful: Latest Friends and family topics - Breast Cancer Now forum. You can also call our breast care nurses who are here to answer any questions or just to chat on 0808 800 6000.
We’re thinking of you,
Lucy
