Took me about 6 months to trust T, but I could see from the very first session that he understood me and would be able to help.

I agree that the thing with the headset seems a bit wierd. I think it's strange to try an intervention of any kind in the very first session before you know one another at all. But that might be just me - as I said it took me about 6 months to start trusting my T!

In some CBT therapy in the NHS you get 6 - 8 sessions, so I guess it is interventions right from the get-go.
