Thanks for sharing your story and I’m sorry that your husband’s addiction is making you so ill and uncertain.
If you would like some help for yourself please contact us at Icarus Trust as we are a charity that offers support to people going through what you are having to deal with addiction in the family.
We have trained people called Family Friends and you could speak with one of them if you get in touch. They may be able to help you answer your questions and would be able to tell you what other support is there for you.
You can get in touch on contact@icarustrust.org
Good luck.
