Help me out with my finances- advice

First of all, I went from working full time 50+ hours a week. I was making good money. It was a temporary position and didn’t have a savings built yet. Now, I have no job, well a part time job only raking in $900/month. I can live decently on $1,500/month. Rent, car payment, and insurance is $920. So that means, food, gas, dog food, phone bill, and other things need to under $550. Which is possible because dog food and phone bill is $70 combined. My boyfriend splits food with me sometimes (but usually I pay for all food for the month). Anyway, how can I make an extra almost $600/monthly? I’ve been looking for other jobs and honestly I have gotten 0 responses and applied to 20+ places. I’ve tried transcription and proofreading but I wasn’t qualified enough to pass the classes and I need money fairly immediately. I have like $20 left in my bank account after paying staple bills. What do I do?? (Babysitting is out of the question as I am a nanny and those jobs are full)
