Recovery is possible
Recovery from alcoholism is absolutely possible for even the most seemingly doomed case. Honesty, open mindedness, and willingness is all that is required.
All the fears you have about not being able to live and have a great life without alcohol are simply erroneous fears and not the experience of those who have recovered from alcoholism.
Stick with it and keep at it a day at a time. It’s a brilliant life. If it wasn’t I wouldn’t bother!
