Thank you so much your replies have maybe eased my pain a lil.
I kinda knew what was coming I guess I just hoped there was another way.
I've told her many a time I can't watch her kill herself and today I've had no contact, I think walking away is my only option. I know she has people round there now getting her alcohol and I can't stand by and watch that.
I never guessed how hard this would be and feel a failure for not being able to help . Someone replied that our help was the last thing they need and I can kinda see that. I'm still getting abuse but I've stopped contact, I don't deserve that anymore. She text this morning saying she's going into rehab but I've heard it before and don't think she has. Thank you to you all for the support and advice :,(
