$30 loan until Friday

Been having trouble with my daily pay app. I JUST got things in order with my finances, but my daily pays been entirely fucky lately. After gas money I had $70 left. Did all my moving yesterday. Checked back today and its at $0. I called them and got told "Oh, im so sorry. But the money will be on your next check." My next check doesnt come until Friday and I need some small groceries so I can eat the next 3/4 days.

I use cashapp if thats alright.
