Welcome to SR christmaslights, know that you are not alone in what is up with you right now. I too was scared to death of getting and staying sober, the fears I learned were nothing but my alcoholism trying to convince me to continue to drink.
I like you weant to a doctor, he suggested I go into detox, detox suggested I go to AA & get a sponsor to find a long term solution for my drinking and my life. I did just that, in AA I found hope, I also found out that being sober is the best thing I have ever done for myself and my family & friends.
Feeling like I need some anonymous support
You know that AA stands for Alcoholics
Anonymous right?
Why not try some meetings? What do you have to lose? A drinking problem? What do you have to gain? Possibly a solution to your drinking and life problems along with making new sober friends to do things with.
