retaliated and destroyed for calling osha

i work for a major national freight trucking co.i have complained to my boss about severe safety violations to no avail.i contacted osha several times.my boss told me he was going to build a file against me to get me fired because i called osha.he has made my life unbearable at work,harrassing and writing warning letters and forcing supervisors under him to do the same. the violations have not been fixed. many co-workers have been injured with at least one fatality. i was recently injured after he put me in a dangerouse tractor he knew about. he denied my workmans comp.after5months i beat him in a hearing on my comp without a lawyer. i have suffered severe physical and emotional trauma because of him and am on anxiety meds. the company is fully aware of all going on and are daily violating many d.o.t. laws. the tractor he made me drive had an mvi safety sticker expired for 5 months. i told him. he made me drive it anyway although it had been previously written up as dangerous. i told him i would call d.o.t. and he told me i better watch my back because im fucking with the big boys now. i am still unable to work and my credit,assetts,family life and mental stability have been destroyed because i complained about safety.
