I drank (wine) at home alone and after about six months of drinking, I had progressed to drinking in the morning to stop the awful anxiety.
I was constantly ashamed of myself and hated myself, wishing I were dead. I thought I was no good to anyone and might as well drink myself to death and be done with it.
I finally reached the point where I wanted to be sober more than I wanted to drink. That was over 11 yrs ago.
I hope your wife decides to stop drinking.
