Hey Ginny, lots of folks come here thinking sobriety causes things to get better; eventually it does for most. At least for the alcoholic.
However, this first year can be pretty rough all around for everyone. You just lost a major component, alcohol, of a 27 year marriage. Lots of unhappy stuff has been hidden behind the disaster of alcohol . . . not fun for most of us to face this.
Please get all the help and support you can for yourself. This is not easy . . . as you seem to have realized.
