Hi Liz, welcome to the forum, everyone here has a loved one with addictions.
I am so sorry to read your story. This is a very stressful time for you and the family. I wanted you to know that there’s no need to feel alone in this nightmare.
My son is 28 and has alcohol and cocaine addictions, I know how this evil drug can turn our sons into people we don’t recognise anymore. They become selfish, unfeeling, aggressive, run up debt, and expect you to pay it. They will blame you for all their problems. The truth is, they always hurt those who are closest to them. I’m sorry to say in my experience, until they realise they have a problem, nothing you say will make them change.
It would be difficult to put him out the house, but sometimes you need to put your own health and well-being first. He needs to know you love him but hate what addiction is doing to him.
The Icarus trust posts here and the adfam forum offers help and advice for families. I post on the Theresa thread, there are several of us mums all with sons with addictions. Everyone is so understanding and supportive.
Please stay strong.
