Kirsty.... as some of the posts have mentioned.... we all take to withdrawl in different ways depending on circumstance, situations, relationships, drinking habits, physiology, etc etc in other words a million different reasons. If alcoholism was easy to beat why would we be here... except to enjoy our sunny personalities!
It will get better.... no question.... the anxiety and all the other 'head stuff' will pass and maybe a counsellor can help you with this. You maybe repressing some of the things that happened when you were drinking and so on and so on.
I am not an AA person as my spiritual side is more eastern, but the aforementioned posts offer good things.... but what is true in all of the successes is that faith and focus are key and how you apply that is you doing what is comfortable for you, and give the comfort when the 'head stuff' comes calling.
Take pride in your journey so far.... the sober road never ends but grants us a wonderful journey.... so head up and see what is around you, many people taking the same journey that have many words of wisdom and years of strength.
Keep the faith....as you find it...
