Hi Anna,
I am sorry to read your blog and can see that you are in a difficult situation. I work for a charity called The Icarus Trust that provides support for people like yourself who are having to deal with the addictive behaviour of a family member or friend.
If you think it would be helpful, we do have people who you could talk to that would give you some support and may be help you find a way ahead.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope that this is helpful.
Good luck.
The Icarus Trust
