I think its great you sent an email right after session. I think you being able to talk about how you felt telling him the attachment stuff and how you thought he reacted is very good therapy stuff and really important. I would just try to distract yourself so you dont' drive yourself crazy till next session....

Just so you don't feel alone.. I had serious issues trusting my T. and I hated the feeling of connection. Alarms would go off in my head....like danger ..danger but it won't always feel like that .

You can work through those feelings with your T.
