End of life travel

Hello, my name is Benjamin, I am 35; and I have been Diagnosed recently with terminal cancer.  An anonymous benefactor has donated to me all his saved airline miles so I can go on a trip of a lifetime.  I will be traveling around the Pacific Rim for 12 to 15 weeks if all goes as planned and my health holds up.   I  would very much like to raise money for the American Caner Society while I also ask for some help myself.  The American Cancer Society helped me while I was doing all my treatments and I really love what they did for me and what they do for so many others.  I am hoping to raise funds for hotels and food and general expenses so I can afford the trip.  I would like to raise enough to make a large donation of all unused donations to the American Cancer Society when I return.  I estimate that it will cost roughly 1,000 usd per week  for everything.  I honestly do not know however.   My disability benefits are very small and barley cover my monthly bills at home.  Any and all donations would be very much appreciated and the more we raise the more goes to other people in need; like I was myself when my diagnosis first came in.  The American Cancer Society helped me with so much it is impossible to convey.  I've never been very good at asking for help and the ACS made it comfortable and easy and the advice they gave was invaluable.
I'm hoping to start my journey around the first of December 2018.  Time is fleeting these days.  
Anyone that donates I would be happy to share all my photos with you.  
I guess that is it.  Ill update as i learn more about this process and my plans.  Thank you for your time.

Update:
I will be traveling to Tahiti for a few days.  Then on to Auckland New Zealand.  New Zealand backpacking for two weeks then flying into Melbourne Australia.  Backpacking Australia for two weeks then on to Singapore.  From here I am unsure due to my doctors strong advice to truncate my trip due to recent scans and blood work.  If I can achieve a good turnaround from the sudden down swing of my health, I hope to backpack from Singapore through Malaysia into Thailand up to Bangkok.  From Bangkok to Cambodia onto Vietnam.  Backpacking from Ho Chi Man city to Hanoi.  From which I will fly to Tokyo to hopefully ski for two weeks.  Upon which I will fly to Calgary Alberta as my last stop before returning back to New Hampshire.
Again, thank you for your time
