Hi,
I’m so sorry that you have been going through all of this with your son and for such a long time. It must be so hard for you.
I work for a charity called The Icarus Trust which supports the families and friends of addicts, people like yourself. If you get in touch with us we could put you in touch with one of our trained experienced volunteers. Talking with one of them might help you to sort out what you want to do next.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope that you can get some help. All the best.
