Mertzie, I am sure that you know that it is not you or your friendship that she has abandoned....she has abandoned herself or at least the self that you knew and loved......and it is alright for you to be angry, we are all angry at addiction.....just don't get stuck on angry, allow yourself to feel the anger and then move on in your recovery.....You can't change the past, but you can ruin the present by worrying over the future.....
