Hi Kia,
I am so sorry to read your post and to know how hard life is for you at the moment. Its very sad that you have no one you can talk to about this but there is help and support out there. The Icarus Trust is a charity set up for people like yourself who are having to deal with a family member or friend’s addictions.
We offer a free service called ‘Family Friends’. These are our experienced trained volunteers who you could talk with if you get in touch. Talking things through with someone who understands what you are dealing with might help you make some sense of things and find a way ahead. Its good to talk! Also they would be able to signpost you to other services that are available.
You can contact us on help@icarustrust.org or visit the website http://www.icarustrust.org
I hope that you can get some support for yourself.
