Help My Best friend Dean Penson medical costs

Hi I’m raising for my life long best friend. He has been on a holiday to Thailand and unfortunately become ill. He has no holiday insurance and is currently having blood and platelet transfusions and various tests. He desperately needs to get home and to a NHS Hospital asap. His bloods are a problem atm, the hospital are querying possible leukaemia. He is struggling to see as he has had a bleed behind both eyes due to blood thinning. I am flying to Thailand to support him and because the hospital have said someone has to escort him home in the condition he is in. Those that know me know I raise a lot for charity I’m asking to raise for my friend to pay for the hospital costs and for me to get him home. I have spent over £1600 myself to help him so far and would appreciate any support as his mum and dad don’t have the funds on their pension. He is a good man, and if he could, he would do the same for all his friends.
