High functioning alcoholics

Quite possibly. Yet it's hard to know, everyone has a secret life, I am a highly functioning drunk. My one friend loves now that I am on nights I can talk with him more, but one day I may piss him off and he's not one to hide when he is pissed off with me. I've even had to say to him, you know whatever anger you feel is yours, even if I know I have contributed by being drunk. Your emotions are always your own in how you respond. I think many drunks could learn to learn that lesson, but it's by no means for me to judge them.

But if you are feeling about their health and want to be there for them. Listen and be there. If it becomes too much, set a boundary for yourself, and if you love them try to find words you think they will listen. Also remember, if they don't listen, it was never you.

No matter what expect some push back, denial is a river that never ends. But a river never ending also offers many stones, shores, bridges, they can (and you) to find.
