IMHO a phone call would be a great place to start as long as you are prepared that the sponsor may not want to work with you in a sponsee sponsor type relationship any longer. That is probably the worst thing that would happen if your sponsor works a program. One thing you may find from the sound of things is someone that cares about you and wants to see you sober (I get this from the phone calls after you went out that the sponsor made). Hiding or avoiding the sponsor only will hurt you in the long run. Good luck with what ever you choose and welcome back to the program. It does truly work when you apply the steps and principles to your life.
