Hello,
I’m so sorry to hear of your bereavement, it must be terrifying for you worrying about your son’s addiction. I just wonder if you have had any bereavement counselling which you should be able to get if you speak to your gp.
You may also like to contact us at The Icarus Trust. We are a charity that supports people going through what you are , trying to support a family members’s addiction. We have people you could talk with and they would be able to tell you what other help is out there.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I really hope that both you and your son can get some help.
All the best to you.
