Thanks JS. Yeah, I think it was ethically wrong too. Evidently he was curious about how I was getting on. Fine until he turned up actually!

I can contact T if I need to. At the end of the session we did both just say how confused we were about what had occurred, and he said he is seeing his supervisor this afternoon, so I'm hoping that'll help him to make some sense of it from his side. I feel ok at the moment, but it's possibly like a false ok? It feels a bit like my brain has decided that's all I can cope with so I'm going to feel fine now. Like a light switch.
