Zachry Construction Corporation ZCC I was unfairly fired after working almost 5 years. I can’t receive unemployment because a project manager who wasn’t even present is claiming to be a witness that I quit!!!San Antonio TX

I apply for job at different company but they say that their boss won't hire me, Carlos told them I sleep with all my bosses. 
My superintendent said he was trying to get me back on, Carlos is saying that I can't until I complete rehab. 
I was fired by Carlos Lomeli bc of a disagreement about his brother, who HE hired to be MY helper NOT because of anything else. I'm so humiliated to even tell anyone the stuff being said about me by my former boss.
Now Benny Garcia a project manager is claiming to be a witness that I quit for another job. That guy wasn't even present when I was fired and I even called hr immediately bc Carlos was trying to make me turn in my truck and phone immediately so I was stranded in Austin hundreds of miles from my family after working over 20hours !!! (Hank from HR blocked me when I asked him to be a witness for me.) Ever since I got transferred to Texas I had been putting up with sexual harassment, toxic work environments, and discrimination that by the time I was fired my spirit was broken. I was bullied and singled out and constantly being blamed for anything they could to try to get me to quit. Now I can't even draw unemployment bc of lies. I didn't spend thanksgiving with my dying mother bc I spent it working. I gave my everything for that company and I can't even get one person to just investigate. Abel Luna from HR is a very mean man and refused to help. I don't know if this even matters but it's so messed up.
