Machinist,
I joined here a few years ago like you but I was not ready to stop drinking. I finally hit the point where you are now about four months ago. My sobriety pretty much started with the doctor's visit. I was extremely nervous but did actually manage to come clean with her. How could she help me if I wasn't going to tell her what was going on?
Doctors are trained to be very objective. If they've been practicing for more than a few years, they have seen it all. Good for you for finally going. I think it's a really good first step.
I put off going to the doctor for about five years because I was worried that that would mean I would need to stop drinking. Once I finally was actually ready to stop going to the doctor didn't bother me as much. After I got the rundown of just what state my health was in, it was not good but not Terminal yet, I knew I just couldn't continue. There is something empowering about saying it out loud to a professional.
