Hi Wagtail,
Thanks for posting. I’m sorry that your son’s addiction has such an impact on your life and that you find it difficult to talk to your friends about it.
I work for Icarus Trust a charity that provides support for people dealing with addiction in their family. if you get in touch you could speak with one of our trained and experienced Family friends who would listen and help you to find a way forward.
You can contact Icarus Trust on help@icarustrust.org or visit our website http://www.icarustrust.org
I hope this helps. Good luck.
