Emma Spiegler from Kings Langley set up an online support group for Children of Addicted Parents (coap.co.uk) two years ago. The aim, she said, was to provide a forum for those in a similar situation.
"I don't think anyone realises how scarred the family and friends of an alcoholic can become," Ms Spiegler confided. "At one point, I found it very hard to express the pain I was feeling, so I used the website and poetry to convey this and to let others know they are not alone."
Her mother - who has been sober for two-and-a-half years - is pleased by her recognition. Although her parents divorced when she was four, "my father has always been there for me and has been very supportive".
Ms Spiegler received her award from Emmerdale actress Georgia Slowe. Part of the prize for the winners was a visit to Anne Frank House in Amsterdam, which she found "amazing. It made me feel privileged to think we all stood in the place where Anne collected her thoughts which have touched so many millions."
She works for Jewish Care as a family care officer.
