Hi Lainey,
Thank you for posting. I know that what you are going through is really hard but hopefully I can offer you some support if you think it would be helpful.
I work for a charity called The Icarus Trust. We offer support to people, like yourself , who are having to deal with a family member’s addiction because we know how hard it is. We have people called Family Friends who are trained and very experienced. If you contact us I can put you in touch with one of them. Talking with them might help you to find a way forward and they would be able to signpost you to whta other help is available.
You can contact Icarus Trust on help@icarustrust.org or visit our website http://www.icarustrust.org
Wishing you all the best.
