Hi Trev90,
Well done on being clean for 2 months, that’s really positive, keep going. I think if you do continue as you are you will find that your anxiety will get better as well.
I am the Mum of an addict, drugs and alcohol and it ruins lives, it is an evil drug, but they will only stop when they want too.
Would he join any groups like NA or anything, perhaps you could go together, most meetings are held via zoom at the moment.
My Son does meetings every day and he finds them very useful.
There are fantastic people on here who are really good to talk too, I only joined last week and have found it really helpful.
Keep going for you, take care.
