Hi Sk21,
Welcome to the Forum, it’s a great place to share your story, and you will find many other people in the same situation. Read through some of the other threads on here, there are so many people going through it, which is very sad.
I am the Mum of an addict (alcohol and cocaine), he is doing well at the moment, but it has taken a lot to get to where he is now, and he has only got here by admitting he has a problem and needed help. Until they realise they need help and want to get back their life, you are banging your head against a brick wall.
As you know taking drugs is not a cheap hobby, and money becomes the b all and end all, this is what I experienced with my Son.
Please don’t think your awful for sharing your story, I hope you feel better for sharing, I know I did.
Please take care of yourself and think about what you want more, because I’m afraid to say that most of the time they only think of themselves.
The Icarus Trust is another place that you might find helpful.
Take care
