Hi Stacey,
That is a very difficult and tough situation. It’s a good step that you’re able to talk about, and there are people who can try and help you. The Icarus Trust is a charity which provides a support and signposting service for families who struggle with addiction, as it clearly affects more than just the addict. Please get in touch with them, and you will be provided with a Family Friend who can support you. You can drop them an email on info@icarustrust.org or go to their website http://www.icaurstrust.org.
I hope this provides the help and support you need.
