any grounds to stand on?

Long story short... I did orientation in jan,this year,drove 5 mos, went broke(yes...I leased) am on the verge of losing home now.anyhow,I went as a contractor to a 'local' co. already got screwed out of a days pay.most loads were overweight,so skip the scales.no weigh policy cuz it takes too much time.I'm desperate.load fromga. to tx,ga and fla ok, but ticket in ms. boss says loads gotta be delivered.aftere zig-zagging thru ms.and la. i drop load,a day later than was so-called scheduled.was to get a load back but it dissapeared.the a\c was out in truck(had issues for 4 weeks and company hadn't put it the shop ..yet) ok.this was a fri bout 4pm when i find theres no backhaul.will know more in the morn,i'm told. around 10am i'm told theres nothing and since no one works on the weekend i'd just have to sit.I'm the reason theres no load, i'm told cuz i delivered late.cant do that i said, not gonna sit in the truck in texas in july with no way to survive, no fridge,a\c. anyhow one of 2 options...drive back and turn in truck ar abandon in texas and never drive again.i drove.now i'm being charged for the fuel(not being paid)Now what do i do?any help is appreciated.

 

it wasn't a lease and what other option did i have?drive or lose my job. but, i get what you're saying.thanx
