Starting to give up

Listen no sob story here, just a cold hard life problem and I don't know what to do!! My wife on friday morning left out to take my son to finally get his hearing aids, have insurance but still took $1000.00 dollars to get, he was without for over a year, mind you it took us that long to save enough money to get them, ok here is where the problem is: Our van overheated on the highway, she calls, I go out to check it out, found a hose leak, I later that afternoon go to fix the leak with JB Weld, it works I'm releived, but oh no when it starts I have little power, I try taking off, my friend stops me, smoke and water coming out the tail pipe. CRACKED HEAD bad news. Cost to fix $1000-$2500 dollars. We still owe roughly $5000.00 dollars 1 years payment, the note is in her step dads name, he won't help us get a new note with trade of our blown van. A high intrest note in our name we could get but we still have a payment on a undrivable van of $515.00 a month, not possible. I have a 1991 ford ranger which will get her to work for now, but a family of 5 won't fit as you know. She works has a decent income coming in, I stay at home and watch my 3 boys and work a job 3 nights a week. With all bills coming in we have no extra money, please know it took us a year to save the thousand needed for my sons hearing aids. What do you do, I know have 3 kids at home every day withoot transportation. We were so close to getting ahead we had 1 year to pay on the van, what a blessing to come we thought. Oh by the way our credit is shot because our house we bought was taken from us when my wife was fired from her past employer. This is not some scam, I'm just looking for some solutions. Someone to fix our Van with a lowpayment plan option, someone with an extra ride, with a low payment plan, any usefull help please, Myself and family would gladly meet and talk about in more detail later. Please I'm not looking for help because were druggies or bumbs, just a normal problem in America, without any more ideas on what to do, except wait and see if a MIRACLE happens. Thank you for reading. KcMitch
