Actually, why 'break the news' to anyone. Just continue working on your recovery. You will change. Those that care will see it down the road and comment on it (the real friends).
If offered a 'drink' by your 'new friends' a simple "No Thank You" should suffice. If not, find different friends.
It is no big deal. As time goes on your family will see the change.
Our ACTIONS, show more than any words we could ever say.
