I turned it around at 48 and life is great. You’re 35 so can have a long and happy life. You haven’t done any permanent damage. Just do what you can to get through these first few weeks as withdrawal is tough due to cravings and lack of sleep. But don’t be tempted to have a quick drink as a “reward” for so many days or whatever. You’re alcohol dependent regrettably which means no more alcohol ever.

I was a total mess in the past due to drinking, but things changed literally within a few months. Just get through those first weeks.
