Hi Carly,
I think sobriety is so much more than not drinking. I would not have been brave enough to go out with people who were drinking when I was in early sobriety. It was too stressful to me to be watching other people drink.
If you think that you are not an alcoholic, then Nogard's suggestion, and decide to stay sober for 3 months. See how it goes and you will have your answer. If you are alcoholic, we have lots of support here for you.
