unfair termination

My name is cory williams I am thirty three years old. At the young age of seventeen I was responsible for a one vehicle car accident involving alcohol. A dear friend passed away as a result. I was charged and convicted as an adult of involuntary manslaughter. I was sentanced to ten years in prison ,probated for five. I completed my conditions and paid my debt to society. I feel the judge understood that I was not a threat to society due to the sentancing. Two years later , in 1996 I applied for a job At the san angelo state supported living center in carlsbad tx. I was twenty years old. I informed the facility and the state of my past conviction four diffrent times through out my tenure at this facility. I have recieved numerouse promotions, bought a beautiful home two blocks from work, got married and have a two year old son and a daughter on the way.I made this my career. Well after sixteen years of dedicated service the state fired me because of a bar to employment conviction I recieved as a minor. I am writing this blog for advice and or connectios to someoone who can help. any advice or assistance will be appreciated
