The important point to remember is that addicts already punish themselves waaaaaaaaay more than anyone in the real world ever could.
Like, in my own experience, it’s like having a spade in my head that constantly smashes me in my face me every few minutes. It’s absolutely punishing.
I genuinely thought I was one of the worst human beings alive.
Referring to them as deadbeats is not the right way to go because it:
a) reinforces those punishing beliefs even more
b) reinforces the isolation and separation, which is a key element in the problem
c) provides an excuse to keep going through stereotypes and stigma (“once an addict, always an addict” etc.)
d) addicts, by our very nature, fight. Pushing an addict is like poking an angry snake. It doesn’t help anyone. Playing the snake calming music does though (ie being nice).
Edit:
One of the reasons I’m still clean is because of the guilt and shame I felt about how badly I treated people. People who were genuinely very nice to me. It takes time to see it, but it’s very important to be kind and to not judge. It’s tough, especially when an addict hurts someone so much and so often.
Of course what you’ve been through sounds like hell. And Addiction doesn’t just affect the individual. It affects everyone around them, unfortunately.
