Grant my last wish. Fulfill my promise.

When I was young I was always asked if I had three wishes what would they be.  They were childish wishes but today I would like to ask that you grant me one wish only and that will be my final wish.  I was diagnosed 2 1/2 months ago with small cell carcinoma with a survival rate of 6 months to two years and it is incurable which means eventually I will pass away from the disease.  I promised my wife I would take her on a trip to the west to show her some of gods great country she has never seen before but I lived for the day not for tomorrow.  I would love to fulfill my promise to her and share some quality time together to make some lasting memories for both her and I. The cost is high but the expenses break out as follows to the best I can figure and you will see I am not trying to get rich on this website.

I have proof signed by 5 doctors to the diagnosis and I am currently under stepped up treatments of chemo therapy to try and get ahead of the disease and it does take a toll on me but I will not give up.  I will fight this with all I have and make this a statistic but at the same time I must face reality and take the prognosis seriously if I am to meet that promise.  I need your help to do that though.  I had a go fund me and had many friends donate to it raising $1600.00 so far so I am only 18,400 away from my goal, you please help.  This is urgent to me and if you cannot donate I do understand but please if you could pass this on to your friends and family that would be extremely appreciated.  Thank you for your time and attention and God Bless you all.
