My situation same as the guy that stayed at garbage center.
I work two jobs to pay for the rental and work nonstop until fall sick just to pay for rental cause Singapore government let me wait for many years without housing.
I been homeless since I eighteen years old and had to stay at a friends place until the age of 35. I keep calling HDB for help but that time they say i too young to apply for housing.
During this period I stay with others untill i reach tbe age 37,i been abused by others whom i staying with. And almost got raped by a landlord.
In end up afraid to stay with others and end up in the sex line to pay for high rental so i can stay alone to rent the whole flat
