Hi NB.....
You may NOT need to recover from anything. If you are not obsessing about how your husband is doing in his program, if you can let him own his addiction and his recovery without interfering or worrying about any little sign of relapse, then I think you are just fine!
I like B66's suggestion of just thanking people for their concern and then changing the subject.
Congratulations to your husband on his sober time!!!!!
Hugs, HG
