Hi Bananacake,
So sorry to read your story and to see how difficult it is for you to be in your own home at the moment. This must be very stressful for you. If you need to talk with anyone The Icarus Trust is a charity that supports friends and family of addicts. Please contact us if you think it would help to talk with people who understand what you are going through.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
