That was always the same for me...whether i quit for 4 days or 4 months life would just happen and i didn't know how to deal with it...it might be the thrill of getting money and posessions that i wanted or the low of some sort of life problem like yours...
The anxiety was always there...the drinking helped for a while then later it made the anxiety worse...anxiety will get worse when you quit then will get better but it will still be there...like a doc once asked a friend of mine "do you still feel any anxiety about anything?", my friend answered "not at all i have a way for coping with anxiety now and it is fine"...then doc replied "so you still feel anxiety then!"...
Getting sober and pretending that the anxiety has gone and living like the boy in the bubble trying to avoid any and all life issues isn't living...we need to change our very core and for that most of us need help...AA worked for me along with a CBT counselor...good luck:-)
