Hi Woo,
I’m so sorry to read your post and see how badly affected and scared you are due to your son’s drug habit. I’m so glad that you have found this forum as the people on here are very supportive. If you would like any more support please contact us at Icarus Trust as we are a charity that helps people dealing with addiction in their family. If you get in touch one of our trained and experienced Family Friends would contact you. Maybe speaking with one of them would help you to answer some of your questions and find a way ahead. They will let you know what other support is available for you and your son.
You can contact Icarus Trust on help@icarustrust.org or visit our website http://www.icarustrust.org
Wishing you and your family all the best.
