Hi,
So sorry to read your post and to see how difficult life is for you and your family because of your brothers addictions. It must be very tough for you all. If you would like to have someone to talk with that would understand what you are going through maybe you’d like to contact us at Icarus Trust. We are a charity that supports people like yourself who are having to deal with addiction in their family. One of our trained and experienced Family Friends would talk with you if you get in touch, and maybe that will help you to know what to do next.
You can contact us on contact@icarustrust.org
Good luck.
