Another recovering NCer here.
I had no choice to become an alcoholic, it's pernicious, it sneaks up on you like that, it generally happens when you are young and feels FUN and GREAT and a fucking middle finger to the world. It takes a while before you realise your 'fuck you' has become a 'fuck it all' and then, 'fuck those bastards they don't understand me, they don't understand ME, ME, I'm a precious flower I can't live by their fucking rules', then to 'Fuck them anyway, they never understood me', then to 'Fuck it all'.
I do think there's a central hurt behind addicts, something that drives them on to oblivion, and that, coupled with a genetic and familial disposition can lead to things spiralling out of control. I've seen it time and time again and it's never a linear descent, it's a series of ever deepening and ever lengthening steps that take you to the bottom, I've seen the denial and the desperate attempts at justification, the lies to the self (because it's easier than facing the truth, because when you face the truth, you actually HAVE to make amends for all the havoc you've caused, sometimes it's much easier to forget that in the bottom of another bottle, or baggie or whatever the poison is).
BUT, the ultimate truth is, no matter why you got where you did, you chose to keep on going there, and you knew you kept on choosing to go there because the alternative was too difficult, too unpalatable, too hard. The act of not doing that would have been a FUCKING EFFORT and that effort was too much, because it's always easier to return to the thing that requires nothing from you but perversely takes everything from you.
People do recover from addiction, people do that every day, they go to meetings, they make amends, they find meaning and build bridges.
But only if that's what they really want to do.
When you're in the throes it's VERY difficult to pull yourself out.
But not impossible, there's always that voice that says, 'I don't want this, I don't want this to be my memorial'. ALWAYS.
Find that voice if you want to. It's up to you.
