My Medical fund

My name is William Slee, 51yrs, single father of 4, 3girls/1boy, & am in need of some financial help.
June 2013 was diagnosed with rectal cancer. After undergoing chemotherapy/radiation treatments, April 2014 underwent surgery to remove rectum & part large intestine, was given colostomy bag, & followed up with more chemo & given all clear Nov 14. Following 6mthly blood test in May 2015 the cancer was found to have returned in liver (3tumors). Commenced more chemo/radiation & had minor operation to reduce blood flow to tumors in preparation for major liver surgery.
Oct 2015 had liver surgery. Opened up, but was deemed inoperable as not enough healthy liver (30%) to sustain life & closed up. Continued chemo until possible surgery later. Unfortunately later scans revealed another operation/transplant was not an option and given 12-18mths, (Nov 2015) & have been continuing with chemo since.
Scans taken Feb 2017, have showed cancer has now spread to lungs & chemo doing little to nothing to slow/stop it. So have ceased chemo to gain quality of life instead, & have been referred to palative care & concentrate on pain management.
I have been trying to keep on top of things but am struggling a bit now. Up until operation in Oct 15 was still working on & off when well enough. Now on Disability Pension recieving $940 p/frtnght with $800 paid straight to rent & ongoing medical expenses taking rest. My son(19) does reside with me whom too is on a benefit as studying Enrolled Nursing course at TAFE helps out with food etc. We have exhausted all savings & my superannuation payment recieved Jan 16 on day to day expenses, household bills, car rego/repairs etc.
Have applied, & on priority public housing list, but they, as us, are unsure when suitable accommodation will become available.
I dont want to leave children with outstanding bills/debts or my funeral expenses, so after a friend told me about Go Fund Me, I thought i'd best give it a try, before its too late.
Many thanks, Bill.
