Got a job, but...

It's extremely slow and I don't get hourly. Just commission pay for the dogs I bathe. I'm not getting paid this week either... I only got this job cause I was lucky enough that a local place was finally hiring for once. I'd have to get a second job to actually get a stable income, but with the job market I'm not sure how. Yes, I've tried redoing my resume and tailoring it to specific places, gotten promising interviews that led to nowhere, even tried job fairs. I get the same unhelpful (and usually rude) 'advice' and for some reason people just don't believe when I say people just really don't be hiring these days. I'm not sure where else I can look. I even tried applying for things I'm not comfortable with (due to extreme anxiety) and applying for places out of town despite my vehicle being old. Instacart only pays so much and a lot of the time, the gas money outweighs what I get. Once again, I'm at a loss.
