First off, I know very well the vulnerability when trying to beat an addiction... it's definitely been the biggest challenge in my life, by far
I was with my first T during a relapse, someone who claimed addictions as one of his specialty. It did not come into the picture initially because I got and stayed sober on my own (and using other tools) when I started seeing him and for a good while... but then I had a relapse. He was clearly very ignorant and poorly trained in that area as I found out, and very dismissive of reactions and vulnerabilities associated with a relapse, he actually played a lot of narcissistic mind games with me in that state, trying to show me "who the boss is"... I left in the end and found someone else who did know what he was doing and was helpful, without claiming a role of authority. I would not allow a therapist to test me repeatedly and to go on an extended power trip. This T clearly plays head games with you as far as I can see from the posts and is causing you stress, it's much more than just having the phone on in case of emergencies.
