Hi Dolly,
Thanks for sharing your story. This sounds very hard for your parents to cope with and I can see why you are so worried for them as well as your brother.
If you would like to talk to a trained person who has lots of experience of what you and your family are going through please contact The Icarus Trust. We are a charity that helps the families and friends of addicts because we know how tough dealing with a loved one’s addiction is.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
Wishing you and your family all the best.
