Welcome to SR Adicta. Glad to hear you have a sponsor, are you taking the steps with her? For me meetings and a sponsor helped a lot, but taking the steps for me was the key. I am seeing now why the old timers who have taken the steps have that peace and serenity spoken of.
One suggestion is to get into the MIDDLE of the fellowship and the steps, open up to your sponsor and in a general way open up in meetings as well, one reason NA & AA work is we learn from others how they dealt with things we are dealing with.
