Hi
So sorry to read your sad story but am glad that you have found support on this forum.
If you would like more support please contact us at Icarus Trust. We are a charity that offers help to people, like you, dealing with addiction in the family. It can be such a lonely place so we have trained and experienced Family friends who you could talk with if you get in touch. They would understand what you are going though.
You can contact Icarus Trust on help@icarustrust.org or visit our website http://www.icarustrust.org
Good luck.
