Hi Amanda.
I had similar thoughts after twenty five years without drinking. I imagined I could drink safely, that if things got out of hand I'd be able to rein it in, and that because I had all that time, I could probably manage my drinking this time around. Unfortunately, I kept drinking for three more years, during which time I destroyed everything good in my life.
For me, not doing the things that got me sober was my downfall. I severed all my connections with AA after about thirteen years, which slowly began my relapse. The final act of that relapse, picking up the drink, didn't happen for twelve more years.
Coming back and getting sober was the most difficult thing I've ever done. It was an impossible struggle...extremely painful, and I'd lost all hope.
You didn't say what lead up to your relapse, or that you'd been using supports, treatment or a program to achieve and maintain your sobriety. If you don't have those things in place, then you're doing yourself a tremendous disservice.
Come back and find a way to stay.
