I'm relatively new to sobriety, so I don't claim to speak from personal experience. But I work in mental health, and there is a reason alcohol and drug abuse are often called "self medicating". Many, many addicts have underlying issues and/or mental illness that are part of the reason they started using. There ARE safe, effective treatments for anxiety (and booze isn't one of them.). I strongly encourage you to find a therapist and be honest about what you've told us. There are better solutions than going back to drinking.
I wish you all the best!
