I have been here many of times. Unfortunately "friends" that I feel who had encouraged me to drink whilst trying to stop (them knowing my drinking leads to self destruction) I have had to delete from my life.
Now most of my friends who are close to me encourage me NOT to drink w as they don't want a night of abuse, drama etc and obviously they care about me.
If she is that bothered about you drinking it seems to me she has a problem herself.
