Natty's Fight

Please help me help my brother. His name is Nathanial and he has lived with a deadly form of epilepsy called Intractable Seizures and as a result has had brain damage for 23 years.
Nat's life has consisted of being in and out of hospitals, lots of surgery and medication and has recently caught the flu which then caused double phneumonia. So he is fighting for his life on a heart/lung machine called Ecmo. He is on kidney dialysis and a ventilator to keep him alive. He is still in a critical condition but he is a fighter and we believe he will get through this. So I'm asking for help, my parents are Nathanial's support group and have dedicated there lives to helping him. However, after losing their home, property and their belongings in the Warrumbungle bush fires last year the finances are very tight, as they can't work to pay for medical bills, accomodation and supplies.
If you could help with any small donation we would be very grateful, every cent helps, so please please please and thank you.
