Hey stewy
Nothing changes when nothing changes. That's not a slap down, it's just an observation borne of my own experience.
I'd love for you to just be able to stop without changing anything else in your life, but I honestly think you're past that point now.
Maybe the bust up with your dad could be a starting point for change?
I'm sure your parents would support you going to AA or some other regular meeting based group for example?
I know you've baulked at this before but maybe outpatient rehab couldn't hurt either?
Sure both things involve change, but a change is what you need.
