"Drinking myself to death seems in some ways attractive."
I used to say this sort of thing. I wonder, therefore, why I never went for it? Perhaps because so much of my life was a fantasy that, when faced with the thought of doing a real thing with real consequences, it pulled me up short.
I notice that you say "wine makes it feel better" and yet you are on, for want of a better word, a problem drinking thread, rather than a "1000 reasons I love wine" thread.
I would say that, based on that post alone, you are very definitely at some sort of rock bottom, because you seem to be in a position where you hate drink and cannot imagine a life without it - this is what is described in the book "Alcoholics Anonymous" as "the jumping off place" where the alcoholic "will wish for the end." Please be aware that I am not defining you as an alcoholic or that you should go to AA; only saying that you have certain things in common with people who DO describe themselves that way.
That said, rock bottom is a bit of a misnomer; there is no rock bottom so low that, with a bit of ingenuity, you can't make it lower still. And there are plenty of us who, having found quite a shallow rock bottom, bounced along it for quite a period of time.
You say you need help and support and don't know how to get it. Well, it's right here. Many of us also find AA helpful, though I am aware that you have already decided this is not for you.
Just out of interest, apart from wetting the bed, how many of the other scenarios do you tick?
