It's Hard to Stop selling drugs and Fighting

I sold drugs from the age of 14 until the age of 48. I fought from the age of 5 until 52. I struggle with both till this day especially fighting. 

Today I had an issue at work and this back stabbing female Causal decided to spread rumors about me and lie on me.  

I was angry and wanted to quit my job and go fight this woman but I didn't.  

I am ghetto with a capital G and decided and thought of Revenge.  I knew I only had to make a few phone calls and we would have fought her bad. 

Three people stopped me from fighting and they were my Pastor,  my Best Friend,  and my teacher. 

While I was in my anger faze I was talking to my boss over the phone and she told me I need my job and not to allow anyone to cost me my income. 

"I don't need my job I have ways to make money. " that was literally the first time in five years that it entered my mind to sell drugs. 

I wasn't being mean or angry but I meant it.  I will NOT stay at a job just because. I would rather sell drugs then be unhappy.  Now the truth is I would find another job before I resorted to selling drugs but it bothered me that it came to my mind so quickly. 

I'm a Christian who is struggling to change my life but when I'm angry,  scared,  or hurt I think of either one or both.
