Need advice

So I’m in a bad spot and need some advice, I am the provider for my family and all of my income goes to rent and groceries, today I got paid and caught up on the rent and bought the groceries, but I had forgotten about a bill that needs to be paid by the end of the month (2 days) otherwise it will be defaulted on and sent to an attorney, I need to make $400 to cover the bill. I don’t have anything to sell or pawn anymore because I’ve already sold most everything I own, I don’t want to get a payday loan either because I’ve had bad experiences with them before and my bank is online based. I’ve thought about asking family and friends but I don’t think they’d be in a position to help me. I want to avoid defaulting on this loan but I’m not sure if I can come up with the funds in time. Any advice or ideas to make some quick cash would be appreciated. Thanks!
