I am too. Big time. Rush came out of treatment sounding like a recovering addict. Lately, however, he has been sounding like an addict on the road to relapse. I hope he's going to a meeting a day, and I hope he's working the steps. He really needs to concentrate on step one: Surrender. I sense he is still thinking he can control his disease. He can't. He's got a big ego and he's got to lose that -- with respect to his addiction -- if he's gonna make it.
Just before you posted, I was thinking the same thing. He is losing his sense of powerlessness, and finding his rage at the "outside" forces that tripped him up to be more important. This doesn't bode well for him. I wish him well, but he indeed sounds like someone who now thinks he has it under enough control to use again. But everyone is different, I don't want to predict failure, just am sad that there seems to be a path to it that he's ready to walk.
