Addiction is a coping mechanism.
It is not weakness or a moral failing. Addiction is not a choice, although with rare mental and behavioral health education, we can avoid making lifestyle decisions that set us up for disaster. Addiction has very little to do with genetics, and much more to do with generational trauma and familial patterns that can result in a family tree dripping with alcoholics.
That first paragraph is thick with stuff it took me over a decade to learn. You don’t have to understand it all. But if you can’t reject the fallacy that addiction is about willpower, genes and morality, then you’re stuck, and none of the rest of this is going to make any sense.
