This might not work if OP is an introvert. I'm an introvert myself and group therapies are the worst as it only makes me stressed out that in turn makes any problem even worse "I've never known an alcoholic who actually stopped for any length of time who did not go through AA." I do, quite many in fact, because AA is not very popular outside USA. What matters most is to always have somebody by your side who cares about you and can help whenever needed -- the form of it (AA, friends, family, therapist etc.) doesn't matter that much.
