Hi fbc83,
The Icarus Trust has a free “Family Friend” service which is giving you someone to talk to, let everything out and then signpost you to additional help if you want. They are people who have been in situations with addictions in their families, so are able to relate on one level of another.
You can contact them via email info@icarustrust.org or have a look at their website http://www.icarustrust.org
Good luck!
