You're doing great Asa. You are also spot on about the alcohol being a cause of the anxiety, rather than a cure.
I gave it about 6 months off the booze and then started to see a natural therapist to get some of my other health concerns under control. There are plenty of options available that aren't as blunt force as some of the prescription stuff. By no means take this as a substitute for medical advice, but I just wanted to say give your body a chance to heal from the beating and when things get a little clearer you may be able to attack the residual problems. It just takes some time to work out which are residual and which are the ones caused by the alcohol
Also, meditation can help. There is a free app called Smiling Mind which has all sorts of simple meditations you can do from 1-2 minutes through to more advanced stuff. I found it worked wonders for calming my mind.
