Unsure where to post this, 10yr vet, 2m miles, possesion of alcohol on psp, is my carreer over?

So during a level 1 inspection at a wiegh the dot officer found that i had a case of beer in my side box. Got a 24 hr O.O.S. citation and no state side ticket. This was all legit, i had the beer in there and took responsability for it.
Now i know it doesnt matter, but i do not drink, i picked up a load at anhieser bush in ny and they were giving away free cases, so i grabbed one, put it in side box and forgot about it for 2 weeks untill the inspection.
Now i was terminated by my employer at the time "due to saftey rating". Since then i have been tuened down time and time again often with no reason given. The ones who do give reason sometimes explain that their underwriters will not approve of my record.
Ok, i get that, but does that mean i am now unhireable? Is my trucking career actually over? Going independant is possible for me but not really an option due to the "start up financing" ill need to turn wheels untill i begin to generate revenue.
Any input, feedback, opinions or suggestions will be welcome and appriceated. This whole ordeal has been quite frustrating and imo very unreasonable.

 

Please any feedback will be appriceated

 

I live in Akron, Ohio, have always been reagonal/dedicated while available to run coast to coast. No wrecks, never failed a screen, i have had some minor traffic tickets regarding things like disobeying traffic control devices and driving on marked lanes though i have had those charges reduced and/or dismissed. My dmv record is good with 0 points and 0 moving violations.
The only other thing that i can even think of is a speed warning and overwieght that is on my psp. I was not issued a ticket for either and both are reported falsely. The speed warning was for 6 over the limit, not the 15+ that it says and the overwieght was for 1700 on drives, not the 2500+ they claimed. I have been through the works for those last 2 issues and i already that because i was not issued a state side ticket they are uncontestable through data Qs.
At the time of the overwieght and speed warning i was fairly ignorant of the way c.s.a./psp worked and was told by those dot officers that since i wasnt issued a ticket,there were no repercussions. So i was relieved yet ignorant of the impacts.
Now, finding employment just seems impossible. And evidently most companies treat this offence as a dui/dwi
