Cloel,
from somebody who has been there....
If you think about it...i mean REALLY think about it....the only true rock bottom is death. Everything else is just false floors. It just keeps getting worse and in ways you didn't even think of.
It would be 1000% better if you said with honesty that you realize you drink too much and want to be a better role model. To tell them you have quit drinking altogether and has removed alcohol from the home. That your attending group therapy meetings.
And this is true too....
The pain the alcohol is covering up was created by alcohol in the first place. Instead of crashing through false floors, wondering how bad does it need to get before a quit sticks, you could stop digging the hole.
You know it WILL get worse. Just stop digging now and you save yourself from hitting rock bottom. What ever that may actually end up being. Probably as bad as you imagine along with other issues not planned for. It will be much harder to climb out of that hole than the one you dug for yourself already.
