if you’ve ever interacted with homeless (or addicts), you’d understand that the vast majority are not like you or me. Mental issues seem to be prevalent.
I only helped cook for homeless people. Some addicts, even when alcohol was drug number one. Mostly victims. Sometimes of their own desire to do the wrong thing. Some victims of bad luck. Victims of parental or marital abuse. Too many things gone wrong for that person not to succumb...
Some had Korsakov, Others ADHD or depression. There's a bit more room in treatment facilities over here, I guess. Of course, some didn't want treatment.
Simple bad luck would be the exception and easier to address. If you personally know any addicts, many of them have mental issues that are amplified by drug use.
The addicts I encountered mostly ended in very sad stories. It can take a while, though.
A lot of them are good people and are quite intelligent. Dealing with mental issues is easier said than done. Unfortunately, I lost one of my childhood friends recently for this reason. You can lead a horse to water but…
I was fairly close to my neighbour across the street many years ago. His 16 year old daughter was lost to heroin. So many people tried. Her family was devastated cause they kept up hope even when it was very bad. Her dad passed away soon after. A broken man, having lost his wife a decade earlier.
Just the loss of her mother drove her to drugs. It wasn't the drug that killed her. She was murdered. The murderer was never found.
My condolences with your loss.
