I'm almost there, just need a little boost

So my truck broke down last year right before Thanksgiving. I put everything I had into getting it repaired,  which was $12,000.  When I got it out of shop, the engine blew up 2 days later. The diagnosis was wrong on repaired, which resulted in fixing something that wasn't the issue and losing $12k. It put me in a bind because now I had no money to fix truck and no income. Company got me a rental truck in the end of January. I was $6,000 in the hole from the company with trailer and insurance payments and finally in the middle of May got caught up on all my bills. I was 3 months behind on everything. I have been trying to save up for a down payment for a new truck, company is helping out as well but I have to get $21,000 on my part. I've already saved up $$8,000. I found a truck and put a hold on it because right now trucks are hard to get. Waiting time is months out on inventory coming in. Truck is supposed to be in July 5th. Just don't know if I'll be able to get the rest of the $13,000 by then. I believe I can get another $8,000 this month but might be short which is why I'm asking for help to get the remaining $5,000. Any help is greatly appreciated. This will help me get back on the road to support my family better. Thank you
