All the emotions that you're feeling are the very same emotions that alcohol subdued, and which you wished to subdue by drowning them with an anesthetic. Now that alcohol is no longer in your body they're rising to the surface, some slowly, some rapidly. What you're experiencing is the emotional turmoil that has not been sorted through and dealt with. It'll take time and effort to address the various issues that you have, but you will achieve it, as long as you don't drink.
You could go it alone, but that would not be advisable. Staying with AA, for the initial 12 months, would be better than risking it all on your own. Expressing the anger/fear/resentment/loneliness/frustration/guilt etc etc is healthy. Try to find a sponsor in AA, or an experienced member to talk to. Once the ball starts rolling it'll gather momentum. However, you need to start it rolling as it wont move on it's own. Think Newtons First Law of Motion.
''An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction, unless acted upon by an unbalanced force.
You must become that force.
