I lost a shitty job at a somewhat desperate time in my life too, don't be discouraged. I owed my parents a few thousand and was so happy to finally get a job but I got fired a month later because the supervisors and general manager were lazy people that didn't help out or do their jobs really. I got some good, legal revenge on the GM though which was very satisfying.

Anyways. Find a job that will teach you skills that apply to other, better paying jobs or give you work tickets. Road construction or even operating equipment on golf courses is a good way to make decent money now but also operating skills are attractive on a resume to get better paying and high skilled jobs.

I personally went from being unemployed at 18, worked at a golf course for the summer that I was 18, unemployed the next winter but receiving EI payments, road construction when I was 19 making a few more an hour and I got the job because I operated the big fairway mowers at a golf course so they figured I could run a packer. When the season was ending I got a job as a propane delivery driver in a class 5 vehicle. From that job I got a forklift ticket and overhead crane ticket which landed me a job recertifying fracturing iron at a smaller company which eventually got me a better paying same job at a bigger frac iron recert company. I worked there until an actual frac company started doing some hiring and I got hired on when I was 20 because of my previous knowledge of the iron, for lift ticket, overhead crane ticket and heavy equipment operating experience. I've been here for 4 years now making over 100k CAD (don't expect to make the same, every situation is different) and now I my for lift, overhead crane, picker ticket which I could use that experience to become a journeyman crane operator if I wanted, my class 1, h2s, first aid, general oilfield driving, skid car training (last two are considered driving courses and look good to your insurance) and a whole slew of other tickets that could land me a well paying job with leverage to negotiate. I'm 24 now with a house and renters that pay my mortgage, a paid off 2010 car, over 50k in savings and I'm planning on buying a C7 Corvette in a year or two. I know I get paid more than what most people would expect but I also live in one of the more expensive parts of Canada. When I was 19, not working and owed my parents money I never thought I'd have a new car or a house until my 40s.

The biggest thing is to just take positives from every job you work, keep looking for a better paying job that your skills can help you land and don't stop until you get into a comfortable paying job and even then keep excelling and improving.
