Loan £20 repay on 11/9 UK bank transfer/paypal for food

So embarrassed to be writing this but I'm struggling just now, recently moved house for a fresh start 3 weeks ago and don't get paid until next Friday and have two small sons at 3&5 to look after. had to finally take a plunge at this because I'm at my wits end and I don't really know where to turn as I've never been so up against it in my life.
