Hi,
Thank you for sharing your story. It must be really hard for you trying to support your son with his drinking and drugs, especially as he doesn’t acknowledge he has a problem.
You might find it useful to contact The Icarus Trust, where you could be put in touch with one of our experienced trained volunteers. We are a charity that provides support for people who are having to deal with the effect of another’s addiction and talking with one of our people might help you to find a way ahead.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope that this helps.
