Hi and welcome,
The Big Book has a passage that describes the feeling of not being able to imagine your life with or without the drink. I'm sure someone else on this site can provide the proper quote.
I'm not a BB thumper, but it is a perfect description of the feeling that most of us felt when we first thought about giving up drinking. So I understand. I have not too long in sobriety, almost three months. And my life has changed for the better. I feel better, no more hangovers, more money, lost weight, etc., but the main difference is my state of mind and the lessening of my anxiety.
I've found AA to be a great support, along with this site. AA isn't for everyone, but does provide a great support network and a lot of good advice.
Give sobriety a try. The bars and liquor stores will always be there. You have nothing to lose and yourself to gain.
