A chance for a cure of my leukaemia

I was diagnosed with T cell leukaemia at the age of 24 in 2017 and had chemotherapy. Unfortunately it relapsed in 2019 and I underwent a bone marrow transplant. Unfortunately the cancer came back again in February 2020 and I had some more chemotherapy to keep it at bay and cancer hit me for the fourth time in June 2020 and now it has gone to my nerves giving me a facial droop. There is a drug called Nelerabine which my consultant recommended but due to the cost of it (130000 pounds for 6 courses - required treatment) it is not available under NHS England.  This drug can provide me with possible cure and allow me to live my life. My situation is extremely urgent. Without this treatment, my option is only palliation. It is likely that I have only got weeks/few months left. I spent the last 2 years and a half being severely unwell and unable to work. I purely want to be normal and be able to work, live with my family and my loved one.
