Medical expenses

My name is Tammy. My boyfriend, Chris Miller and I have 4 children between us, including our new 4 month old son. The past few weeks have been fairly rough financially. 2 weeks ago Chris passed out at his job Heil Trailer and was transported to Starr by ambulance. They didn't have any answers which has lead to many doctors visits with required up front copays. With no answers yet Chris hasn't been able to return to work due to the danger of his job (welder). He is not on a paid leave and will not bring in any income the next two weeks (at least $1,200 loss) and our household runs on mine and his together. We have had to pay $245 in copay totals so far with future appointments set up for specialists. We have not received the bills for the tests and ambulance ride yet but we know it will be a good chunk of money. To top off all the concerns with his health, our vehicle that we still owe payments on slung a rod and motor locked up just last week. We are dependent on having 2 vehicles because we both work, I in Charleston and him in Athens. The break down could be due to a recent recall that the corporate will have to investigate before we have answers and we're unsure how long that will take but we will have to tow the car from Knoxville to whereever they want us to. Anything will help us at this point. Anything and everything will be greatly appreciated.
