Hi Arlene,
This must be so distressing for you. I work for The Icarus Trust, a charity that supports the families and friends of addicts. If you get in touch with us, one of our trained and experienced people may be able to help and answer some of your questions.
You can contact The Icarus Trust on help@icarustrust.org or visit our website http://www.icarustrust.org
I hope this is useful.
Good luck.
