Quick jobs to make money // I'm struggling

I feel shamed to even asking this, but does anyone have ideas on how i can make money rather quickly? Like odd jobs or where to find them? I am a nanny and i didn't expect for the family i work for to go on vacation for 3 weeks with no type of pay (i have ALWAYS gotten at least half a weeks pay from the previous family) but of course i will not ask for it. This is one downfall of being a nanny 😩 i completely care for their 5 children, literally do everything.....and the family isn't even giving me a Christmas bonus. I know I probably sound stuck-up, but as a nanny we tried to go by the same rules as any other corporate business. of course holiday pay isn't mandatory, but because I do such a personal job you would think that the family I work for would be a little bit considerate. And yes i know they can afford it, they are actual, literal, millionaires. I'm talking the type of people who don't even see their kids because they work so much, they have an entire staff to cater to them....... literally.

They know that i am struggling as it is getting on my feet since i am only 21 and live on my own. Anyway, i HAVE to find a way to make at least $600 by January 1st. since I'm off for three weeks starting now, i will not have enough for my bills. I just paid all my bills last week, so imagine not getting paid at all in between your bills being do 😩😩 and on top of that I already haven't eaten a meal in 3 days since i needed gas money to work.

This sucks so much, I've been crying and praying so hard the past few days. Not only will i be late on all my bills, but i don't even have groceries and now there's no way in hell I'll be able to get my little sister something for Christmas.

This is so stressful. All i wanted to do this year was give back, all i wanted to do was have enough money left over to help a family in need. Turns out I'm the family in need 🤦🏽‍♀️😭😭😭

Sorry for venting. Anyway, does anyone have advice on what i could possibly do?

EDIT: thank you everyone so much. I really appreciate the feedback and ideas. I looked into Amazon flex delivery and that's definitely the best option....no interview needed, you just start working. Thank you all again!!
