Hi Lime and Joanna,
Please feel free to contact The Icarus Trust if you feel it would be helpful. We are a charity that supports friends and families of people with addictive behaviours and have a team of experienced people you could talk with.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope that you can find some support and not feel so alone.
Good luck to you both.
