Needing help this once please

Hello, 
I am looking for help, just this once, and heard about this site. Really hoping I could recieve it. 
A couple of weeks ago, I was at a gas station, well long story short, some one stole my wallet with all my money in it. I take care of my 3 nieces due to their mother being in jail. And I have no help from other family members. (They want no part in her, my sisters, life.) Now, my rent is coming up and I need to make it in order not to get kicked out with no where to go with 3 little girls. My landlord is very strict on rent. And it's pay by month and he would have every right to kick me out if I don't pay on time. 
I'm needing 500$. 
I work very hard. I do have a job. But, with it coming up so quickly, I won't have the money in time. 

I really do thank anyone, out there, who can help me. And I know it's a long shot but I thought I would try it. 

My cash app is cash.me/$sarahlee313

Again, thank you for who helps. I promise it's just this once.
