Yes, they work at the same clinic. Current T thought is would be a good idea to have one or more sessions with PrevT to talk about my attachment and to find out where it comes from and also to help me and PrevT to have a good closure (though I don't think PrevT really cares about that, to me it seems like she can distance herself/her feelings from her clients). And because It's so hard for me, current T will be there too so she can help me if I need it.
I don't know if I'm really not going to have PrevT as my T again. I don't want to stop having her as my T, even if I'm angry/upset/disappointed right now.
