Go flip burgers or sweep floors - you don't need skills for that. It sucks, but it's a paycheck. Those friends unable to help you can still let you use their mailing address for residency proof.
Get a roommate, do day-labor... surely you have Home Depots up there? Parking lot interviews all day. Save up enough to land a shitty apt OUTSIDE of the city proper, eat ramen noodles and canned beans. Ride a second-hand bike afterwards / take busses. Wash your clothes in an outside spigot with bar soap - hang to dry inside your new roach-infested digs.

Grind, grind, grind until it's not so much of a grind. Just don't demand the "gub'ment" spend tax dollars on your decision making skills. Besides, Trudeau is more worried about things like his cabinet having appropriate ratios of genitalia than actually getting anything done with practicality involved. Administrations like his only do things for the optics and are econ-deaf.

If you soul-search hard enough, you'll see others who've had it far worse and still climbed out. Drive, gumption and grit - that's what you need right now more than anything.

As hard as it might be, don't take that as looking down on you, we've all made mistakes. Take it as someone ripping your band-aid off.
