Help rebuild my life

In 2012, after a career in financial markets technology I had stop full-time work due to a major health crisis involving cardiac, endocrine, neurological and the early stages of oesophageal cancer. In the years since I have lost everything I had worked for, am still encumbered with $80,000 in debt and now live in public housing on Disability Support with no quality of life and a negative income.
This definitely isn't easy for me, as I am a proud man, but the fact is that I simply cannot survive at present and am hoping to rebuild my life, to learn new skills, and to fulfill my dream of becoming a writer.
I urgently need support with ongoing medical expenses, the purchase of a computer and hopefully a companion animal.
Any assistance would be greatly appreciated.
