Hi,
Really sorry to read your post.
If you think it would help please contact us at The Icarus Trust. We are a charity that provides support for people in your situation as we know that having to deal with an addict in the family is really tough.
We have trained and experienced people that you could talk with if you get in touch. They would be able to tell you what other help is available.
You can contact Icarus Trust on help@icarustrust.org or visit our website http://www.icarustrust.org
All the best.
