Thankyou for sharing your story. I’m so sorry that your partner’s addiction is causing you so much anxiety. That must be so hard for you and it’s good that you have found this forum so you can see that you are not alone in how you are feeling.
I work for a charity called Icarus Trust who support families dealing with addiction so you might want to get in touch with us. We have trained and experienced people called Family Friends who would talk with you and let you know what other help we could give.
You can contact Icarus Trust on help@icarustrust.org or visit our website http://www.icarustrust.org
All the best to you.
