Life saving drug Pembro - Please help!

I have stage 4 metastatic head and neck cancer. In 2018 I had my voice box and oesophagus removed, this is a life changing surgery and I spent 4 months in hospital. Unfortunately in November 2019 the cancer returned. This is my third battle with throat cancer. My consultant has told me that to survive this I desperately need the immunotherapy drug pembrolizumab (Pembro for short) unfortunately this drug is not covered by my health insurance company OR the HSE. The treatment is costing myself and my family €7,800 per month. Please can you help me fund this treatment, I am a mother to 3 children, I'm only 51 and I don't want to die. Thank you.
