It’s great that you know you need to stop and are working out the next steps.
I’m going to sound a little direct here. Whilst getting a doctor’s appointment and zoom meeting are Important, quitting alcohol is 95% (maybe more) willpower. One of these days you will have to spent a very long and unpleasant evening with no alcohol in the house, and that will be your first day of not drinking. You may well drink again the day after, but you’ll have done that first day and know you can do it again.
So remember the doc and meetings are some help, but it’s mostly up to you.
The great news is, and I remember very well from when i quit two years ago, that those grim anxious days last two or three weeks max. Get through those, and you’ll have a great new life you never imagined.
