Rita, I think that young lady has an incredible mother, and the fact she knew she could call you and be honest without being judged says a lot.
When I drank and used again after 4 years in recovery, I did not tell either of my parents. They had/still have no program of recovery for themselves.
I was out there for 2 months, and finally drug myself back to my home group, and I started over again.
Give that fear to your HP dear.
