Hi Sunshine
I often go through periods of really great therapy session and feel like I'm making progress, then I "shut down" too! I try to rely on my T to bring me "back" ya know? It doesn't always work.

It's a great start to identify that you're doing this though and that means that you aren't really shutting down completely, you're processing this somewhere in yourself so you're thinking anyway.......and imo you're not totally shut down, just in some ways....at least that's what I tell myself, this part of the feeling of being shut down is part of my process and I apparently need it......

Hang in there!
