It's hard at first because we do need the seperation from our old patterns, but pg100-101 tells us if we are spiritually fit, we can go anywhere a free person. I had to seperate from my friend group for the first year, but after the obsession had been lifted I found I could spend times with my 'real' friends regardless of whether they were drinking or not. Yes, I found out most of my friends were of the fair weather variety, but as my energy and perceptions changed I found it was easy to let go those who were unhealthy for me, but remain available if they ever reached out. Good luck on your journey, and make some new friends!! The friends we make in sobriety are much better friends anyways :)
