Asking for more time

Hello my name is Les, I am 54 I have wide spread bone cancer. My son kurtis is 17 and it has been him and me. I was diagnosed with metabolic bone cancer in April, but have had symptoms since November 2017.I have worked as a labourer most of my life and bringing up my son has been a challenging, we have lived but was never able to buy a house or land. We currently live in a small house bus at my brothers place of work.. Basically I'm asking for ten thousand dollars so I can have the exstreem vitamin c injections which are around 280 per injection will need three per week for approximately 6 to 12 weeks.. I need to spend more time with my son I don't want to leave him alone not this early in his life. Yours sincerely les... Thank you...
