Me, being the daughter of an alcoholic would say that it is really sad and sometimes there is nothing you can do, I honestly mostly prefer to close my eyes for the facts because I can't change a thing and feeling hurt doesn't help.
I don't know if your friend is just too insecure and only drinks too much in company or a real alcoholic like my dad as well, but I think it is good to try to let her realize how you see it and how others see it. Does she plan to have a view beers in company and then drinks more than planned or does she drink on a daily base?
She might think that she has power over her drinking behaviour like "I can stop whenever I want but I just don't wanna stop" some people just don't know that they are alcoholic. But it is very hard to look into someone head and decide for them what is the problem. A psychologist would maybe be a good idea, as they can be able to let someone understand himself better and force your friend to think about the problem instead to ignore it. Again, this kinda things are hard and there might be nothing you can do.
Sending you hugs and light.
It is really hard, cos I also don't want to push her away either. I can keep trying to talk with her, but yes, it is a choice she needs to make. I do not know if she drinks everyday, I am not around her that much.
Thank you for your advice @xsasj, I really appreciate it xxx
