Hi Kim,
I’m so sorry to read your post about your son’s drug habit and how badly it is affecting you. It must seem really tough but you are not alone and there is help out there.
I work for a charity called The Icarus Trust who try to support people like yourself who are dealing with a family member’s addiction. If you would like to contact us you could talk with one of our experienced people who would be able to answer your questions and tell you about what other help is available.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope this is helpful.
Good luck.
