Lost

I'm 32. I was once employed now I am not. My former employer has done me dirty to say the least. He has essentially put my name along side another former Co worker. Aka his friends son. For 5 years I worked for this company. 4 with this kid. He was trash from the start lying stealing and could not let him out your sight because he would be found lying down or on his phone. Usually both. The only other employees (the good ones) either quit or were "fired." He fake fired his brother hoping that, that would make me quit having to work with this kid. [Back story, my dad was his former boss and there is some resentment to say the least. I'd get phone calls and text late at night, my boss the owner being drunk letting me know how he really feels. Long story short, I have grit and a he'll of a work ethic. I didn't quit, I dug down and did all the extra work. Spoke my concerns when they arose about his shit ability to work. This is a physical demanding job mind you. Crawlspace/mold remediation. Don't need to be smart, just hard working and honest. Fast forward to last year, when I was terminated. I was told it was for bullying this kid. They bullying stated was me saying the crawlspace was musty like his momma. Normal banter we do all the time. No worse than the shit they'd say about me. Now the good stuff. Fuck the job and coworkers what hurts is how little trust my family showed me. I have no friends, no family that I trust or trust/know me evidently and a city full of people in a state I have spent 20 years calling home shunning me out trying to exile me. My dad doesn't talk to me, which honestly as more time goes by I could care less and less. My question now is do I stay or leave everyone in the ducking dust. Im not a runner nor do I want to be seen as one. However I feel I am at a crossroads in life and dont want to miss an opportunity for growth and happiness. Versus what I have been feeling for over a year now.
