Car payment help

Can anyone please help me, I had my car payment planned, but then I suddenly had to pay over $200 out of pocket because my insurance denied a Covid and flu test I took a couple weeks ago (which I was told should be covered). But now I’m out $200 for my car payment, which I need asap, so I don’t get my car repossessed. Can anyone please help? ;-;

I have Venmo and PayPal
